Lock is a local password manager with a clean, cross-platform desktop interface built in CustomTkinter, for Windows, macOS, and Linux. It encrypts all stored credentials with a single master password, so a user needs to remember only one password to access everything. It's aimed at people who want a simple, private password manager that runs entirely on their own machine.
