KeePass

KeePass Password Safe is a free, open-source tool for users who want to securely manage their passwords. It allows saving all passwords in a database that is secured with a master key. The database files are encrypted with the most secure encryption algorithms currently available (AES-256, ChaCha20, and Twofish). The software is free and open source, which means that the entire source code can be reviewed and checked for correct implementation of security features.
