What makes a password strong?
Length matters most. Every extra character multiplies the number of possible passwords, so a random 16-character password is far stronger than a clever 8-character one. The strength meter shows this as entropy in bits, where each extra bit doubles the number of guesses an attacker would need.
GrabKit uses your browser’s cryptographically secure random generator (crypto.getRandomValues), the same kind of randomness used for encryption, so the passwords can’t be predicted.
Staying safe with passwords
Use a different password for every site. When one site is breached, reused passwords let attackers into your other accounts. Use a password manager to store them, so you only need to remember one strong master password.
Turn on two-factor authentication wherever it’s offered. Even if someone learns your password, they would still need the code from your phone or security key.
Frequently asked questions
Is the password generator free?
Yes, completely free. There is no sign-up, no watermark, no daily limit and no premium plan.
Are the passwords sent or saved anywhere?
No. Passwords are generated in your browser with its secure random generator. They are never sent to a server or stored, so only you ever see them.
How long should my password be?
At least 12 characters for everyday accounts, and 16 or more for important ones like email and banking. A password manager makes long passwords easy to use.
Why exclude look-alike characters?
Characters like 0 and O, or 1, l and I, are easy to mix up when you read a password aloud or type it from paper. Leaving them out makes the password slightly weaker for the same length, so add a character or two to make up for it.
What does entropy in bits mean?
It estimates how hard a password is to guess. Each extra bit doubles the number of possibilities, so higher is better, and long random passwords reach high values quickly.
Can I generate several passwords at once?
Yes. Generate a batch and pick the one you like.
