Mot de passe Générateur

Generate strong passwords or memorable passphrases.

Randomness

Bytes come from crypto.getRandomValues with rejection sampling, so mapping bytes onto a character set never introduces modulo bias. Entropy (bits) is length × log2(character-set size), using the set actually used to generate the result — not a guess based on which characters happen to appear. Each checked character type (a-z, A-Z, 0-9, symbols) is guaranteed at least one character in the password; positions are then shuffled so guaranteed characters don't cluster predictably. This is a generation-time estimate, not a formal security proof, and results are never transmitted anywhere.

How to use

• Pick length and which character classes to include.
• Or switch to Passphrase for a sequence of dictionary words.
