Instantly generate a secure, random password with your desired length and character types — all local, in your browser.
Password settings
Choose the length and character types. The password is generated instantly and locally, on your device.
The password is generated randomly in your browser (crypto); it is not sent or saved anywhere. Use a unique password for each account and a password manager.
Handy everyday tools. Simple, fast calculations for common situations. Everything runs instantly in your browser, no account, no data sent.
The password combines characters chosen at random from a set; strength grows with length and character variety:
A 16-character password with letters, digits and symbols has an entropy of ~100 bits — very strong, impossible to brute-force.
A secure password is long, fully random and combines upper and lower case letters, digits and symbols. This generator uses the browser’s cryptographic source for real randomness.
At least 12 characters, and 16 or more for important accounts. The longer the password, the exponentially harder it is to crack by brute force.
Entropy, measured in bits, expresses the password’s unpredictability. Over 60 bits is considered strong, and over 80 bits very strong, hard to crack in practice.
No. The password is created solely in your browser, is not sent to any server and is not stored. Copy it and save it in a trusted password manager.
Length and character variety. A long, random password with multiple character types has a huge number of possible combinations, impossible to guess or crack quickly.
Yes. Adding symbols enlarges the character set and therefore the entropy and strength of the password. Do check, though, that the service accepts all symbols.
You do not have to. Use a password manager that generates them, stores them encrypted and fills them automatically — you only remember one master password.
Because if one service is breached and the password leaks, attackers cannot use the same password for your other accounts. Reusing passwords is risky.
