Best open-source alternatives to 1Password

AliasVault is an open-source, self-hostable password and email alias manager aimed at users who want a privacy-focused alternative to traditional password managers. It helps people create unique identities, generate strong passwords, and create random email aliases for different websites while keeping sensitive data end-to-end encrypted. The project is designed for use across web, browser extensions, and mobile apps, with cloud-hosted and self-hosted deployment options. Its architecture emphasizes zero-knowledge security: the master password never leaves the user’s device, and even received emails are encrypted. The README also highlights autofill support, import from other password managers, and built-in TOTP authentication as part of its broader feature set.
