PassSumo
Support
Get in touch
Something broken, a question, or a feature you want: use the feedback form. It goes straight to the person who writes the code — there is no support queue, because there is no support department. You can leave an email address if you want a reply, or leave it blank and stay anonymous.
Locked out because the master password is lost: there is no way for PassSumo, or anyone else, to recover it or the vault it protects — that is inherent to the KDBX format, not a limitation of this app. The feedback form above is still the right place for anything else — a question about Touch ID, backups, or how a specific entry behaves.
Does PassSumo support key files?
No, and that is a deliberate choice. A key file is only a file on your disk. Any process that can read your files can copy it, whether that is malware, a compromised app, or an AI agent with file access. It adds a step for you, but not a real barrier for an attacker who is already on your machine.
A master password is stronger, but it is still something you type, and anything that watches your keyboard or screen can capture it. The only factor that holds up against software running on your own computer is biometrics backed by secure hardware: Touch ID and Face ID. That is where PassSumo puts its effort: Touch ID unlock on the Mac, and your explicit approval before an AI agent gets access.
If your database is protected by a key file, PassSumo will not open it. To use it with PassSumo, remove the key file in the app that created the database and keep a strong master password.
