Estimated strength: 122 bits
This tool runs entirely in your browser; the value it generates is sent nowhere.
How it works
Cryptographic randomness
Values come from the random number generator of libsodium, the library Passhield's own product uses, with unbiased selection.
Nothing is sent
The tool runs in your browser; it makes no network request and keeps nothing it generates.
Strength in bits
It shows the estimated randomness for your options. 70 bits and above holds even against offline attacks.
Questions people ask
Password or passphrase?
Both are strong when used well. For accounts you keep in a password manager, a long random password is best. For the one thing you must remember (such as your master password), a passphrase of five or six words is both strong and memorable.
How long should a password be?
For a randomly generated password, 16 characters or more is enough for most accounts. Length adds more strength than complexity; 20 characters is a good default where the site allows it.
Where should I keep the password I generated?
In a password manager. A spreadsheet, a notes app or a chat group is no place for passwords; accounts a team shares need a shared, encrypted vault.
You have the password; now share it with your team safely.
In Passhield the generator sits inside the item; the password you create is saved straight into an end-to-end encrypted vault.
