AliasVault
Privacy-first password manager with built-in email aliasing
...It is designed as an end-to-end encrypted system where all sensitive data, including passwords, usernames, notes, and email content, is encrypted on the client side before being transmitted or stored, ensuring that even the server cannot access user data. The platform introduces the concept of “virtual identities,” allowing users to generate unique credentials and email aliases for every service they use, effectively isolating accounts and minimizing the impact of data breaches. AliasVault also includes a built-in email server that receives messages sent to generated aliases and encrypts them immediately, integrating communication and identity management into a single system.
