01 / Length
Password length
Longer is generally stronger. The minimum matches the number of selected groups.
How it works
Generate a secure password in three steps
The secure default is ready to use. Change the controls only when a website has a specific password rule.
- 01 Use the secure default.
A new 20-character password is created with every available character group.
- 02 Match the site’s rules.
Adjust the length or combine lowercase, uppercase, numbers, hyphen, and symbols.
- 03 Copy and store it safely.
Save the password in a trusted password manager and avoid reusing it elsewhere.
01 / Randomness
Create stronger, harder-to-guess passwords
Each password uses secure browser randomness and includes every selected character group. Increasing the length adds more random choices and makes the password harder to guess.
02 / Privacy
Keep generated passwords private
Passwords are generated on your device. Nanomite does not receive, store, or place them in a URL.
03 / Compatibility
Match any website’s password rules
Some sites limit length or punctuation. Select only the groups that site accepts, while keeping the password as long and varied as its rules allow.
