How it works
Choose the supported file from your device.
Use the available settings for the result you need.
Save the completed file directly to your device.
Choose a password length from 8 to 128 characters. Select the uppercase, lowercase, number and symbol groups you want to include, and optionally exclude ambiguous characters. Click Generate Password, review the result, then copy it. Use Regenerate Password to create another option.
Create customizable random passwords without an account. Choose character groups, generate 12-, 16-, 20- or longer passwords, and exclude easily confused characters when needed. Password generation uses the browser's cryptographic random source.
Passwords are generated locally in your browser and are not uploaded to or stored on Nimzoa's application servers by the generator. Copy and handle generated passwords carefully. Website analytics are separate from generated password values.
No. Passwords are generated locally in your browser and are not uploaded or stored by this tool.
It uses the browser's cryptographic random source and unbiased selection, ensures each selected character group appears, and shuffles the result.
Yes. Select Exclude ambiguous characters to leave out examples such as O, 0, I, l and 1.
No. Select Generate Password or Regenerate Password to make a new password using your current settings.
No. It is only an estimate based on selected length and character groups.
Yes. Nimzoa lets you choose any password length from 8 to 128 characters, including 12, 16, 20, and 32 characters. Set your preferred length, select the permitted character groups, and click Generate Password.
Yes. Turn off the Symbols option and keep the character groups you want, such as uppercase letters, lowercase letters, or numbers. The resulting password uses the selected character types. Consider a longer password when using a smaller character pool.
Choose a long password, preferably 16 or more characters when the service allows it, and generate it randomly. Use a different password for every account, store it in a trusted password manager, and enable multifactor authentication where available. No password length or setting guarantees complete security.
A strong password is an important part of protecting an online account. Reusing the same password across multiple websites can increase the damage if one of those services experiences a data breach.
Nimzoa's free online password generator helps you create random passwords with customizable lengths and character types. You can choose uppercase letters, lowercase letters, numbers, and symbols, then generate a password directly in your browser.
The tool supports passwords from 8 to 128 characters and includes an option to exclude easily confused characters.
No account or software installation is required.
Use the slider or length field to select a password length between 8 and 128 characters.
For example, you can create a 12-character, 16-character, 20-character or longer password.
Choose which character groups the password may contain:
Uppercase letters (A–Z)
Lowercase letters (a–z)
Numbers (0–9)
Symbols and special characters
Use the groups accepted by the website or application where you plan to use the password.
Enable the option to exclude easily confused characters, such as certain letters and numbers that look similar.
This may make a password easier to read or enter manually, although excluding characters slightly reduces the available character pool.
Click Generate Password.
Nimzoa creates a new password using the selected settings.
Use Copy Password to copy the result.
Save the password in a reputable password manager or another appropriately protected location. Avoid leaving sensitive passwords in unprotected notes or messages.
To create another password, select Regenerate Password.
A random password generator is a tool that creates passwords by selecting characters from a defined set using a random selection process.
Instead of relying on predictable choices such as names, birthdays, or common words, it generates character combinations that are harder to anticipate.
For example, a randomly generated password might combine uppercase and lowercase letters, numbers, and symbols.
Do not use example passwords printed in articles as real account passwords. Publicly displayed examples are not secret.
Nimzoa's generator is designed to use the browser's cryptographic random source rather than ordinary non-cryptographic randomness.
However, no password generator can guarantee that an account will never be compromised. Account security also depends on the service, the device, how the password is stored, and other protections.
A strong password should generally be long, difficult to predict, and unique to the account where it is used.
Length increases the number of possible character combinations when passwords are generated randomly.
If the website permits it, a randomly generated password of 16 or more characters can be a practical choice.
Avoid reusing a password across email, banking, shopping, and social media accounts.
If one service is compromised, password reuse can expose other accounts.
Names, birthdays, phone numbers, familiar phrases, and common keyboard patterns can be easier for attackers to guess.
A reputable password manager can help you store different passwords without needing to memorize every one.
Where available, enable an additional sign-in factor, preferably a phishing-resistant option such as a passkey or security key.
A strong password is valuable, but it should not be your only account protection.
A 12-character password may be useful when a service has a specific length requirement or limits longer passwords.
To generate one with Nimzoa:
Set the password length to 12.
Choose the permitted character groups.
Click Generate Password.
Copy the result.
Twelve randomly selected characters can provide substantial resistance to guessing, depending on the character set and generation method.
However, longer passwords generally offer a greater margin of protection when the same generation method is used.
A 16-character password is a practical option for many online accounts that support longer passwords.
To create one, set Nimzoa's length control to 16 and select your preferred character types.
For a randomly generated password, increasing the length from 12 to 16 characters greatly increases the number of possible combinations when the character pool remains the same.
A 16-character password is not automatically secure in every situation, but random generation, uniqueness, and safe storage are strong foundations.
For accounts that allow longer passwords, you can choose 20, 24, 32, or more characters.
Nimzoa supports lengths up to 128 characters.
Long random passwords can be particularly convenient when used with a password manager, because you do not have to memorize or manually type them regularly.
Before generating an unusually long password, check whether the receiving service has a maximum length or restrictions on supported characters.
Some websites require passwords to contain particular character types.
Nimzoa lets you select uppercase letters, lowercase letters, numbers, and symbols.
Using both letter cases increases the available character pool compared with using only one case, assuming random selection.
Numbers can be included when a website requires digits or when you want a larger pool of possible characters.
Symbols may include punctuation and other special characters supported by the generator.
Some websites restrict particular symbols. If a generated password is rejected, check that service's password rules and adjust your selections.
Not necessarily.
A sufficiently long, randomly generated password can be strong without symbols. Password length, unpredictability, and uniqueness are more important than following a universal rule that every password must contain every character type.
When a service requires symbols, Nimzoa lets you include them.
Sometimes a website accepts only letters and numbers or restricts certain punctuation marks.
To generate a password without special characters, deselect the Symbols option and leave the permitted character groups enabled.
You can also generate letters-only passwords by disabling Numbers, provided the remaining settings are accepted by the tool.
Restricting the available characters reduces the size of the character pool, so consider using a longer password when permitted.
Ambiguous characters are letters, numbers, or symbols that can be difficult to distinguish visually.
Examples may include:
Uppercase I and lowercase l
The number 1 and similar-looking letters
The number 0 and uppercase O
Nimzoa offers an option to exclude ambiguous characters.
This can be useful when a password must be copied from a printed document or typed manually.
However, excluding ambiguous characters does not inherently make a password stronger. It reduces the number of available characters, although a longer password can help compensate for that reduction.
There is no single password length that guarantees security in every situation.
As a general practice, use the longest unique, randomly generated password that the service reasonably supports and that you can store safely.
For example:
Password Length | Typical Consideration |
|---|---|
8 characters | Available as the tool's minimum; prefer longer when possible |
12 characters | Useful where length restrictions apply |
16 characters | Practical default for many randomly generated passwords |
20 characters | Longer option for compatible services |
32 characters | Suitable when longer passwords are accepted and managed safely |
Up to 128 characters | Available in Nimzoa, subject to the receiving service's limits |
The strength of a password depends on more than length alone. Randomness, uniqueness, password reuse, and account protections also matter.
A random character password and a passphrase are two different approaches.
A random character password combines characters selected from a permitted set.
A passphrase typically uses multiple words, ideally selected independently through a reliable random process.
Long passphrases can be useful when you need something easier to remember or type.
Nimzoa currently generates random character-based passwords. It does not offer a dedicated random-word passphrase generator.
If you need a memorable passphrase, use a tool specifically designed for that purpose.
Password guessing resistance depends partly on how many possible passwords an attacker might need to try.
For uniformly generated random passwords, the number of possible combinations can be estimated as:
Possible combinations = Character pool size ^ Password length
For example, a password using only 26 lowercase English letters has 26 possible characters at each position.
A 12-character password selected uniformly from that pool has:
26^12 possible combinations
This is a mathematical model, not a guarantee of real-world security.
Actual risk depends on factors such as whether the password was generated properly, whether it has been exposed, and how the service protects authentication attempts and stored credentials.
An online password generator's safety depends on its implementation and the environment in which it runs.
Nimzoa's Password Generator is designed to generate passwords locally in your browser using the browser's cryptographic random source.
The generated password is not sent to Nimzoa's application servers for generation or storage.
Nevertheless, browser extensions, compromised devices, clipboard access, malicious software, and unsafe password handling can introduce risks.
Use a trusted device and browser, keep software updated, and store important credentials securely.
No online generator should be described as completely risk-free or unhackable.
Nimzoa's generator is designed to create passwords in your browser without uploading or storing them on Nimzoa's application servers.
The generated value remains available on the page until it is replaced or the relevant browser state changes.
When you use Copy Password, the value is placed on your device's clipboard, where other software or clipboard-history features may be able to access it.
Website analytics are separate from the generated password itself.
For sensitive accounts, move the password into a trusted password manager promptly and avoid sharing it through insecure channels.
Using one password on multiple services increases the risk of account compromise if that password is exposed.
Sequences, keyboard patterns, and personal information are easier to predict than genuinely random choices.
Adding a symbol to a short, predictable password does not necessarily make it strong.
Avoid sending account passwords through ordinary chat messages, emails or shared documents.
Additional authentication protections can reduce risk when a password is stolen.
Avoid storing important passwords in publicly accessible files or unencrypted notes.
Create unique passwords for personal online accounts.
Generate passwords for educational platforms and other services that support password authentication.
Create separate credentials for permitted work accounts, following organizational security policies.
Generate random passwords for development and testing environments, while following appropriate secrets-management practices.
Encourage unique credentials and better password handling across business accounts.
Use the Password Generator above to choose a password length, select allowed character groups, and generate a random password in your browser.
For stronger account protection, use a unique password for each service, store credentials securely, and enable multifactor authentication where available.
