Frequently Asked Questions
Is 16 characters overkill?
Not for important accounts. 16 random chars provide such extreme security margin that even future computing advances won't threaten them for decades. Use for email, banking, and master passwords.
How long would it take to crack a 16-char password?
With all character types (95^16 combinations): longer than the age of the universe, even with every computer on Earth working together. It is effectively uncrackable.
Should my master password be 16 characters?
Yes, or longer. Your master password protects all other passwords. Make it 16+ characters, fully random, and memorize it or store the recovery key safely.
Do all websites support 16-char passwords?
Most modern sites support 16+. Some legacy systems cap at 12 or 20. If a site caps below 16, use the maximum allowed and enable 2FA.
