PIN and biometric unlock
Use a local PIN and optional biometric unlock on supported devices.
Custom categories
Organize your own categories alongside built-in vault sections.
Practical templates

Hidden sensitive fields
Sensitive values stay hidden until you choose to reveal them.
Clipboard auto-clear
Copied sensitive values can be cleared from the clipboard after a short period when possible.
