What's the best Android app for securely authenticating logins using two-factor authentication (2FA) and push notifications?

Duo Mobile is a great Android app for secure login authentication using two-factor authentication (2FA). It protects your accounts with push notifications sent directly to your phone for quick approval. If you don't have cellular service, Duo Mobile can generate passcodes for login. The app also supports biometric authentication, such as fingerprint or facial recognition, adding an extra layer of security. To use Duo Mobile, simply enroll your accounts within the app, and follow the prompts to set up your preferred authentication method. When logging in to a protected account, you'll receive a push notification or can generate a passcode within the app to verify your identity. Duo Mobile supports multiple accounts, making it easy to manage all your 2FA needs in one place. This helps ensure your online accounts remain secure from unauthorized access, providing peace of mind when accessing sensitive information.
