How to use the Password Strength Checker
- Type a password; nothing is sent or stored.
- Read the strength, entropy and crack time estimates.
- Follow the tips to make it stronger.
Frequently asked questions
Is it safe to type my real password?
The check runs entirely in your browser and nothing is sent, but the safest choice is to test a similar password instead.
How is crack time estimated?
From the size of the character set and length, reduced for common passwords, sequences, repeats and years.
What makes a password strong?
Length first. A random phrase of four or more words, or 16+ random characters, from a password manager is ideal.
