Password strength checker
Type or paste a password to see how weak or strong it is, with a clear checklist of what is missing (uppercase, digits, symbols, length...) to make it stronger.
How to check a password's strength
- Type or paste the password you are considering into the field.
- Click the eye icon if you want to look back at what you typed.

The more checks it meets (long enough, has uppercase/lowercase/digits/symbols, not common, no repeated or sequential pattern), the stronger it is rated.
Not yet — it only compares against a short list of very common passwords, not a database of real leaked passwords.
