Strong random passwords and memorable passphrases in your browser — pick character sets, strip ambiguous symbols, and see approximate entropy before you copy.

Recommended: 16+ for regular use, 24+ for critical accounts.
This tool synthesizes secrets using the Web Crypto quality of crypto.getRandomValues, avoiding biased modulo tricks by sampling from adequately large pools. You get transparent entropy estimates for random mode (charset cardinality raised to password length) and approximate wordlist entropy for passphrase narratives.
Unlike simplistic generators, you can strip ambiguous characters where 0/O collisions derail ops runbooks, plus ad‑hoc exclusion lists for environments forbidding quotes or shell metacharacters.
Rotate API keys and service accounts using the Paranoid preset (length ≥ 32, full charset). For human‑handled unlock codes, prefer passphrase mode with six or more tokens from the curated lexicon—users type them reliably during live incidents. Always pair generated material with your vault product’s rotation policies; nothing is stored on our servers.
