Guide
What makes a password strong
A strong password is long, random and unique. Length is the biggest factor: each extra character multiplies the number of possible combinations. Randomness matters because people choose predictable patterns such as names, dates and keyboard sequences that attackers try first.
Strength measured in bits
The strength shown here is an estimate in bits of entropy. It comes from the password length and the size of the character set you picked. Around 75 bits is strong for most accounts, and 100 bits or more is very strong even against heavy guessing.
Store them safely
You do not need to memorize random passwords. Use a password manager to store them, and turn on two-factor authentication for important accounts. Never send a password by email or chat.
Frequently asked questions
Is the password sent or stored anywhere?
No. It is generated in your browser using your device's secure random number generator. It is never sent to our servers and never saved.
How long should a password be?
Use at least 12 characters, and 16 or more for important accounts such as email and banking. Length adds more strength than extra symbols.
Should I reuse a strong password on several sites?
No. If one site leaks it, attackers try it everywhere. Use a different password for each account and keep them in a password manager.
