OneRule Vault
Offline Password Manager
Biometric Unlock Enabled
Unique Feature
Panic Mode
Set a secondary Panic PIN that opens a completely separate decoy vault — filled with harmless dummy entries — if you are ever forced to unlock your device.
Your real vault stays hidden. The person forcing you sees a convincing but harmless decoy. No other mainstream password manager offers this.
