Why choose 16 random characters?
Longer random passwords provide more possible combinations and work well for accounts where software can store and autofill the result.
Compatibility comes first
Some services limit symbols or impose a maximum length. Disable only unsupported groups. Never shorten a generated password after copying it; generate the required length directly.
Store it securely
The generator does not save the result. Copy it into the intended account and a trusted password manager before closing this tab.
