Password strength checker: frequently asked questions
Is it safe to type my password here?
The check runs only in your browser and nothing is sent or stored. Still, avoid testing passwords you use for critical accounts.
What makes a password strong?
Length first: 12+ characters, ideally a passphrase of several random words, with a mix of character types.
What is entropy?
A measure of how unpredictable a password is, in bits. Each extra bit doubles the guesses needed.
Are passphrases better?
Long passphrases of random words are strong and easier to remember than short complex strings.
Should I change passwords regularly?
Change them if there is any sign of a breach. Unique, strong passwords plus two-factor authentication matter more than frequent changes.
Should I use a password manager?
Yes. It lets you use a unique, strong password for every account.
How accurate is the crack time?
It is an estimate. Real attacks use dictionaries and leaked lists, so predictable passwords fall much faster.
Can I generate a strong password?
Yes, with our password generator.
Does it support Arabic text?
Yes. Text is processed as Unicode, so Arabic and other scripts are handled correctly.
Is the password strength checker free?
Yes. It is free with no sign-up and no usage limits for normal use.
