Your dictionary
Map each letter of the alphabet to a word you'll remember. Personal, offline, and never leaves your device.
Instant expansion
Type 3 letters, get 3 words. Your passphrase builds in real time as you type.
Stays private
Locked behind Face ID. Hides itself in the app switcher. Auto-clears your clipboard. No cloud, no servers.
Flexible format
Choose your separator, toggle capitalization, and set a clipboard expiry to match your workflow.
How it works
Build your dictionary
Assign a memorable word to each letter — a → ashen, b → brush, c → cedar. Use words that mean something to you.
Pick your letters
When creating a password, choose 3 letters — maybe from the site name. Type them into the Generator.
Copy your passphrase
LetterPass expands your letters into a full passphrase. Copy it, paste it, and add your own salt at the end.
Remember it forever
Next time, just recall your 3 letters. Open LetterPass, type them in, and your passphrase is back.
