How strong is your password really? Get a score, entropy and crack-time estimate.
The checker measures your password’s character pool (lowercase, uppercase, digits, symbols) and length to compute entropy in bits — the true measure of guessing difficulty.
It then estimates crack time against 10 billion guesses per second (a serious attacker’s rig) and flags common patterns: dictionary words, sequences and repeats.
75+ for important accounts. Anything under 35 can fall in seconds to modern cracking rigs.
The check runs locally and nothing is transmitted — but for peace of mind, test a similar password instead of the real one.
Each extra character multiplies the search space. A 16-character passphrase beats an 8-character symbol soup.
Length beats complexity: a long passphrase outlasts a short cryptic one. Type any password to get an honest strength score, an estimated crack time, and concrete tips to make it stronger — checked locally, never sent anywhere.
