Security notice

How to read these release notes

x2y Authenticator is designed for local-first, offline operation. Authentication secrets are not stored in a remote cloud service as part of normal vault operation. Users should maintain a secure physical copy of their recovery material. Stealth Mode and encrypted backups are security mitigations, not guarantees, and no authenticator can completely protect secrets on a fully compromised device.
