Important: two different kinds of tool
Bitwarden, KeePassXC, Passbolt, Padloc, 2FAS, and PearPass are password managers or authenticators for people and teams, with apps and browser extensions. HashiCorp Vault, Phase, and Keyshade manage secrets for applications and infrastructure. Cozy is a personal cloud that includes password management but is not a dedicated credential manager.
Closest to 1Password
Bitwarden is the closest match: apps and browser extensions on every platform, secure sharing, organizations, passkeys, and official self-hosting. KeePassXC keeps an encrypted vault locally with no cloud, and Passbolt targets team credential sharing with granular permissions.
2FAS: authenticator is open source, the password manager is source available
2FAS Authenticator, for Android, iOS, and browsers, is licensed under GPL-3.0. 2FAS Pass, its password manager, is licensed under the Business Source License 1.1 plus an end user license agreement, so it is source available rather than open source. Both are free and store data locally without an account.
License details
KeePassXC is GPL-2.0 or GPL-3.0, Bitwarden clients are GPL-3.0 and its server is AGPL-3.0, and Passbolt, Padloc, and Cozy are AGPL-3.0. PearPass is Apache-2.0, Keyshade is MPL-2.0, and Phase is MIT with an enterprise license. HashiCorp Vault has been under the Business Source License 1.1 since version 1.15, so it is source available.
Maintenance status
Padloc has had no commits since March 2025, so check it carefully before relying on it. Keyshade's last commit was in April 2026. Bitwarden, KeePassXC, Passbolt, 2FAS, Vault, and Phase were updated within days or weeks of this update.
