A simple password manager that I wrote. Hopefully secure, although no guarantees :)
I am not a cryptography expert - although I have some knowledge about it from studying a little cybersecurity and doing some CTFs
It encrypts the passwords locally (using your master password) before sending them to firebase - so theoretically even if google was hacked they wouldn't have your passwords.
To compile the typescript install deno and run
deno bundle -c deno.jsonc src/index.ts public/index.js
To host the server for development just use a simple http server like
python3 -m http.server 8080
