Set Security Level
You can grant separate security levels to users regardless of the biometric 1:N security level set on the device. If users frequently fail authentication when the device's 1:N security level is set high, consider lowering the 1:1 Security Level to mitigate failed authentications.

Set the desired level in the 1:1 Security Level field. The available values are as follows:
- Device Default
- Lowest
- Low
- Normal
- High
- Highest
Click Save in the upper right corner of the screen to save the settings.

If you set Private Auth Mode in the Credential section to Biometrics, you cannot apply the 1:1 security level as the input user cannot be identified, and you can only apply the 1:1 security level when a card or ID that allows user identification is set in the authentication mode. For more information about Private Auth Mode, refer to the following.

Set an appropriate security level. A higher security level may result in lower fingerprint authentication rates or higher False Rejection Rates (FRR).
