Hi there! I understand you're having trouble with the Fifth Third app not accepting your device login. To get a clearer picture, could you tell me a bit more? For example:

- Are you using the mobile app or accessing through a browser on your device?
- Is this the first time your device is being used, or was it working before?
- Are you receiving any specific error messages when you try to log in?
- Have you tried logging in on a different device or network to see if the issue persists?

Once I have some of these details, I can guide you through the most effective steps to resolve the problem.

device has worked and log in ok in the past several years

Thanks for letting me know your device has worked fine for years and now you’re suddenly facing this issue. That helps narrow things down.

Since it’s been working before, there are a few common reasons this can happen over time: changes in the app or website, security updates, or corrupted cache/cookies on your browser if you’re logging in via browser.

Here’s a straightforward plan to try solving this:

1. Clear Cache and Cookies: If you’re logging in through a browser, cache or cookie corruption can prevent a smooth login. Clearing these often resolves many login hiccups.
- In your browser (WebKit-based on Windows), look for Settings > Privacy > Clear browsing data.
- Select cache and cookies, then clear them.
- Restart your browser and try logging in again.

2. App Update or Reinstall: If you’re using the Fifth Third mobile app, check if there’s an update available. Sometimes older versions have compatibility issues.
- Go to the app store and update it.
- If it’s already updated, try uninstalling and reinstalling the app.

3. Password and Account Verification: If you recently changed your password or if the bank made any security updates (e.g., requiring a new password you haven’t set), it could cause login issues.
- Try using the “Forgot Login” or “Forgot Password” option to reset your credentials securely.

4. Device Registration/Security Prompt: Sometimes, after updates, the bank might require you to re-verify your device or identity.
- Check your email or SMS for any security codes or prompts from Fifth Third.
- Ensure any device verification steps are completed.

If none of these solve the problem, it could be helpful to check if there are any ongoing service issues on Fifth Third’s end or if your account has any restrictions.

Would you like me to guide you through clearing the browser cache and cookies step-by-step or assist with resetting your password? Also, are you using the browser or the mobile app to log in? That info will help me tailor the instructions better.
