About the password generator
Long, random passwords are the best defence against guessing and cracking. This generator uses your device's cryptographically secure random number source and picks every character without bias, so no character is more likely than another.
Each character type you select appears at least once. The password is created on the spot and is never put in the page address or stored, so reload the page to get a new one. Use a different password for every account and keep them in a password manager.
Formula
- Entropy (bits) = length × log₂(size of the character pool)
Example
A 16-character password using all four types draws from a pool of 85 characters, which gives about 103 bits of entropy.
