Biometric Verification bypassed in Trezor Suite with external monitor
Reported on March 9, 2026
Biometric authentication in Trezor Suite could be bypassed when the functionality was not available on the host device. This could happen, for example, when a laptop was connected to an external monitor and its lid was closed. This beat the purpose of biometric authentication which should prevent other users of the host device from unauthorized access to the app.
