Open the existing password generator with its length set to 16 characters. The generator still uses the same cryptographically secure browser randomness and lets you adjust character groups before creating a password.
A 16-character value may meet a service’s length requirement, but password strength also depends on unpredictability and unique use. Follow the destination’s current rules and do not reuse passwords.
The preset changes only the starting length. You can change included character groups and exclusions in the existing generator. Generate locally and store the result in a password manager if you need to keep it.
