Why use a password generator?

A strong password is the first line of defense against the hacking of your online accounts. Yet passwords chosen by humans are often predictable: first names, birth dates, number sequences, or dictionary words. These passwords are vulnerable to dictionary and brute-force attacks, which test millions of combinations per second. A password generator creates random, long, and unpredictable strings that are impossible to guess and extremely costly to crack. The longer and more varied a password (uppercase, lowercase, numbers, symbols), the more the number of possible combinations explodes, making any attack unrealistic. This tool generates secure passwords directly in your browser, without ever transmitting them over the network. You control the length and character types to meet each service's requirements.

When to use a generated password? 8 concrete use cases

Creating a new online account

Generate a unique password for each new service so you never reuse the same one.

Replacing a compromised password

After a data breach, immediately replace the affected password with a new one.

Securing an admin account

Use a very long password (20+ characters) for root, admin, or database access.

Generating an API key or token

Create a complex random string to serve as an application secret or access token.

Creating a secure PIN code

Use the PIN preset to generate a random numeric code that is hard to guess.

Setting up a new Wi‑Fi

Protect your home or business network with a long, random WPA key.

Sharing temporary access

Generate a single-use password for guest access, to be revoked after use.

Meeting a password policy

Adjust length and character types to meet a service's or company's requirements.

Best practices for your passwords

  • Use a unique password for each account: a breach on one service won't compromise the others.
  • Aim for at least 16 characters mixing uppercase, lowercase, numbers, and symbols.
  • Store your passwords in a password manager (like Bitwarden, KeePass, or 1Password) rather than in a file or notebook.
  • Enable two-factor authentication (2FA) wherever possible, in addition to your password.
  • Never share a password via email or unencrypted message, and immediately change any password suspected of being compromised.

Frequently asked questions

What password length is recommended?
Most security experts recommend at least 12 to 16 characters. For sensitive accounts (banking, admin, primary email), aim for 20 characters or more. The longer the password, the more resistant it is to brute-force attacks.
Are my generated passwords sent to your servers?
No. Generation happens entirely in your browser, locally. No password is transmitted over the network or stored on our servers, ensuring complete confidentiality.
What are ambiguous characters and why exclude them?
Ambiguous characters are those that look visually similar, like the number 0 and the letter O, or the number 1 and the letter l. Excluding them makes manual entry easier and avoids errors, useful when you need to type it out.
Is a long password safer than a complex one?
Both matter, but length generally has more impact than complexity. A 20-character lowercase password is often harder to crack than a very complex 8-character one. The ideal combines length and character variety.
Should I change my passwords regularly?
Recommendations have evolved. Rather than systematically changing every 90 days (which encourages weak passwords), it's better to use long, unique passwords and only change them if you suspect compromise or a confirmed breach.
How can I remember random passwords?
You don't have to remember them. Use a password manager that stores them encrypted and fills them in automatically. You only need to memorize a single, long, strong master password.
What is a brute-force attack?
A brute-force attack consists of automatically testing every possible combination of characters until the correct password is found. The longer and more varied the password, the more astronomical the number of combinations, making this type of attack impractical.
Do I need a different password for each site?
Yes, absolutely. Reusing the same password is one of the riskiest mistakes: if a single service suffers a breach, all your other accounts using that password become vulnerable (credential stuffing attack). A unique password per site is essential.
