TSNP (thou shall not pass) – a password rule generator

TSNP is a small tool designed to help people stop reusing passwords by creating a memorable rule, not a stored password.
Instead of saving or generating passwords for you, TSNP shows patterns you can follow:
how to combine a base word, numbers, symbols, and the service name
how to vary passwords per platform without having to remember each one individually

Nothing is stored, nothing is sent anywhere, and the examples shown are only meant to illustrate the rule — not to be copied directly.
The goal is simple:
make better password habits easier to practice, especially for people who don’t want password managers or complex vaults.
You can try it, regenerate patterns, and keep only the logic that makes sense to you.
