If Amazon will not let you sign in on your phone, compare the Shopping app with Amazon’s website in your browser. If only one fails, start with that app or browser. If both fail, check the sign-in method, account details and verification prompt before reinstalling anything.

Start with the sign-in screen
Open the official Shopping app or type the correct Amazon website address yourself. Use the email address or mobile number linked to that account, with the right country code when needed. Follow the method shown: an account may offer a password, passkey or a temporary-password flow.
Amazon’s sign-in help explains checking account details and recovery options. A saved browser password can be old, and a delivery-contact number is not necessarily the account’s sign-in number.
Choose the right next step
| Problem | First check |
|---|---|
| Shopping app fails; website works | Update and restart the app, then retry. |
| Browser loops back to sign-in | Check site cookies, content blockers and the correct Amazon domain. |
| Password rejected everywhere | Use the official password-help or account-recovery flow. |
| Verification code missing | Check the registered destination or an already configured alternative. |
| Device cannot be authenticated | Compare app/browser behavior and record the exact message. |
If the Amazon app cannot authenticate the device
- Close and reopen the app, then install an available update from the official app store.
- Check that the phone’s date and time are correct.
- Try a normal connection rather than a captive Wi-Fi sign-in page.
- Try the website in a current browser to see whether account access itself works.
- If the message persists, contact Amazon through its official support route with the app version and error wording.
The message alone does not prove the phone is banned or the account has been hacked. Clearing app data or reinstalling can sign you out, so make sure you have a usable recovery method first.
If Safari or another mobile browser will not sign in
Allow the site data needed for sign-in and try a normal browser tab. If a content blocker seems involved, test only the relevant site exception. Clear Amazon’s own site data if needed, rather than wiping every website’s cookies as the first step.
If hotel or café Wi-Fi has not completed its own sign-in, use our public Wi-Fi login-page guide before troubleshooting Amazon.
If two-step verification blocks access
Use an alternative you already set up or the recovery route offered on Amazon’s own sign-in screen. Keep recovery details current when you regain access. Our Amazon two-step-verification guide explains the extra sign-in step; disabling it is not a routine login fix.
Amazon provides account recovery after verification fails. Use official pages, and never send your password or a one-time code to someone claiming to fix the account through a chat comment.
