During crucial application workflows, such as confirming a bank transfer, it is recommended to use biometrics as an added layer of security.
Unlike entering a passcode, accessibility services cannot verify any biometric actions. If your platform provides the option to add a description to the biometric screen, it is advisable to use it, as the system prohibits any services from tampering with it.

Residual risks
Malware that has device admin privileges or an accessibility service can disable the use of biometric authentication on the device globally. Therefore, other protections against malicious accessibility services apply.
