LetterPass

LetterPass turns a short sequence of letters into a passphrase you'll never forget. The idea is simple: you build a personal dictionary — one memorable word for each letter of the alphabet. Then you create your own rule for picking letters from any site you log into (for example: first letter + last two letters of the domain, or every other letter of the name). Type those letters into LetterPass and it instantly expands them into your passphrase. The result: a unique, memorable password for every site — derived from a system that lives entirely in your head. How it works 1. Build your dictionary — assign a word to each letter (a → ashen, b → brush, c → cedar). 2. Pick your letter rule — something only you know, applied consistently to every site. 3. Open the Generator and type your letters. LetterPass expands them into a passphrase instantly. 4. Copy, paste, and append your personal salt (e.g. 123!). Done. No two sites produce the same passphrase. And because the system lives in your memory, there's nothing to breach.
