About OTP Helper
OTP Helper is an open-source Android application that automatically copies one-time passwords and codes from SMS messages and notifications. It uses a notification listener to read text from notifications sent by any app, including email apps, and a separate listener for incoming SMS messages.
In both modes, it checks content against ignore rules and matches it against a code-detection pattern, then handles the extracted code according to user settings. It is described as working completely offline without internet permission.
