Biometric authentication
Face ID, Touch ID, fingerprint: unlock BlueMail with the same gesture you trust everywhere else.
Security · Lock Screen
Your email,
Your email,
your eyes only.
BlueMail's secure Lock Screen (passcode or biometric) keeps your mail protected even if your device is lost or borrowed. It's one layer of Blue Guard, on every device, free.
Custom passcode
Set a 4- to 8-digit PIN, separate from your device lock, for an extra layer just for your inbox.
Auto-lock timing
Lock immediately on close, after a few seconds or after a few minutes, configured exactly how you want.
Per-account locks
Lock specific accounts independently — keep work behind an extra barrier without slowing personal mail.
Privacy in notifications
Hide sender and subject from notifications when the app is locked, peek-proof by default.
Background blur
App switcher previews blur automatically, sensitive content stays hidden even at a glance.
