How to use a random password safely

  1. Choose a length and the character types accepted by the service. At least one type must remain selected.
  2. Select Generate new. Each selected character type will appear in the result.
  3. Copy it into the account’s password field and save it in a password manager. Do not reuse it on another account.
  4. Enable the service’s multi-factor authentication where available. Keep recovery codes somewhere safe.

Long, unpredictable passwords help resist guessing, but they cannot protect a compromised device or a phishing page that persuades you to enter them. Open the service through a trusted bookmark or its official app.

What this generator does—and does not—measure

Password mode uses cryptographic randomness to select characters, not names, dates or common passwords. It avoids biased character selection and checks that every selected character group is represented.

We do not display a “centuries to crack” promise. Real attack speed depends on how a service stores passwords, whether attackers are rate-limited, and whether the password is stolen rather than guessed. A generated password is not a security guarantee.

A passphrase uses 6–10 independently selected words from the EFF long word list. Random words are different from a quotation or a sentence you invent. Save the result before changing an account password.

Frequently asked questions

How long should my password be?

Use a long, unique password that the service accepts. This tool defaults to 20 random characters. A length of 8 is offered for compatibility, not recommended as a general security target.

Do I have to include symbols?

Follow the destination’s rules. Length and unpredictability matter; a long random password need not include every type unless the service requires it.

Are my generated passwords stored?

This generator does not save or transmit its output. Copying sends it to your device’s clipboard, which may have history or syncing enabled.

Why does a website reject the result?

Some websites restrict length or certain symbols. Change these options to fit the stated requirements rather than making the password predictable.

Can I use the same strong password everywhere?

No. Reuse means an exposure at one service can threaten other accounts. Generate a different password for each account.

Does this change my TempMail Cloud password?

No. Generating a password here changes nothing in your accounts. Use the relevant service’s password-change process to apply it.
