Open-Source Password Managers Without Accounts
By Mihaly Kertesz · Updated
KeePassXC, KeePass and KeePassDX are open-source options for local database workflows without a vault-provider account. They support different devices and roles. Source availability, binary provenance and account-free storage are separate properties.
Open-source password managers by device
Desktop and mobile clients occupy different parts of a file-based workflow. Copying a database to another device does not turn its desktop application into a mobile client, and specialized fields may behave differently.
| Project | Role to evaluate | Compatibility check |
|---|---|---|
| KeePassXC | Windows/macOS/Linux desktop KDBX | Browser integration and supported credentials |
| KeePass | Database application with edition/plugin choices | Database version and required plugins |
| KeePassDX | Android local KeePass-file client | File provider, filling and desktop interoperability |

Open-source password manager licenses and downloads
A public source project and applicable license support an open-source claim. They do not establish independent review of every release or prove that a downloaded binary matches a particular commit.
Official distribution and verification guidance provide provenance evidence. Popularity and generic security labels do not replace that evidence.

Accounts in open-source password manager workflows
A local database may not require a vault-provider account, while optional transport or an app store still uses one. Vault creation, updates, synchronization and backup access can each have different requirements.
Self-hosting can remove hosted-provider storage while retaining service accounts and server operations. It is not inherently an account-free workflow.
Open-source password manager compatibility
A fictional database with several URLs, a Unicode note, groups and an attachment can show field support across clients. A saved controlled change demonstrates more than a successful first open.
These are documented candidates, not a claim that Passary performed every device test. Compatibility evidence remains specific to the versions and operating systems involved.
Passary and open-source password managers
Passary is our own local-vault product. Its repository is private, so it is not presented as an open-source alternative. Its public security, recovery and download information describe a separate offering.
Account-free operation transfers responsibility for copies and credentials rather than eliminating recovery requirements.
