Mobile access is convenient but brings different security considerations than desktop. This walkthrough targets mobile sign-in safety: from authenticating the app and enabling mobile-friendly 2FA options to fixing push notification issues that prevent you from approving sign-in requests. We’ll also cover what to do when an app fails to open or the sign-in screen freezes.

Verify the app source

Only download exchange apps from official sources: Google Play Store or Apple App Store. Check the developer name, app reviews, and download count. Avoid installing from third-party APK sites. Confirm the app’s permissions — watch for apps that request access beyond what’s needed (for example, SMS or contacts when not required).

Choosing the right mobile 2FA

Many apps support push-based 2FA or in-app approval. These are easy but rely on push delivery. An authenticator app (TOTP) is more robust; consider using an authenticator on a separate device when possible. If a hardware security key supports mobile (via NFC or USB-C), that’s even better for resisting remote attacks.

Troubleshooting push approvals & codes

If push notifications don’t arrive, check the phone’s notification settings and battery optimization rules (Android aggressively restricts background processes). Ensure the device clock is set automatically — time skew breaks time-based codes. If codes don’t match, try resyncing your authenticator app or using backup codes generated earlier.

Safe mobile browsing & in-app webviews

Some apps embed webviews for sign-in. When prompted to enter credentials, confirm the webview shows HTTPS and the expected domain. If you must use a mobile browser, prefer a private browsing window only for login. Avoid copying verification codes into other apps.

Lost or replaced phone

Plan ahead by securely storing recovery codes in your password manager or an encrypted file. If you lose your phone and used authenticator apps without backup, follow the platform’s recovery flow immediately; expect identity verification. Remove the lost device from any "trusted devices" list if possible.

Following these mobile-specific practices keeps your account resilient while letting you enjoy on-the-go access. For device-specific or platform-specific steps, consult verified support articles from the service provider.
