Hi there! I’m here to help you with the login issue you're experiencing on UpToDate. Let’s work through this together.

First, can you confirm if you’ve recently made any changes to your account or if you’re accessing it through a specific network, like a hospital or library? Also, have you tried logging in using a different web browser or device? Sometimes, browser issues can cause login problems.

In the meantime, here are a few steps we can try to troubleshoot the login issue:

1. Close Your Browser: Completely close the browser you are using and then reopen it. This can help refresh any session states.

2. Clear Cache and Cookies: Clearing your browser’s cache and cookies can resolve any old data that might be causing the issue. You can usually find this option in the settings menu under Privacy or Security.

3. Check for Maximum Attempts Error: Sometimes, if you've tried logging in multiple times with incorrect credentials, you might reach a maximum login attempts limit. If you see an error message about that, refer to this guide.

If you've already tried these steps and are still facing issues, it may be a good idea to reset your password or verify your account status. You can request a password reset email by going to their login page and looking for the "Forgot Password" option, or by visiting UpToDate Technical Support.

Please let me know how it goes or if you need further assistance! Are you satisfied with the solutions I provided?

I have the correct username and password but it won't log in. When o press log in, it appears error, that happens only from the cellphome. But in the computer or laptop i can enter just fine

Thanks for the clarification! Since you're able to log in successfully using a computer but having trouble on your phone, it seems like the issue may be specific to the mobile experience. Let’s try a few things to get you logged in from your iPhone.

1. Restart Your iPhone: Sometimes a quick reboot can resolve temporary glitches. Just hold down the power button and swipe to turn it off, then turn it back on.

2. Update UpToDate App: If you’re using the UpToDate app, make sure it's updated to the latest version. You can check for updates in the App Store.

3. Check Internet Connection: Ensure that your phone has a stable internet connection, either Wi-Fi or cellular data, as a poor connection might affect your ability to log in.

4. Try Incognito Mode: If you're using a browser, open a new incognito or private browsing window and try logging in from there. This mode doesn’t use cached data and can help bypass issues related to stored data.

5. Clear Safari Cache: If you're trying to log in via browser, clear the Safari cache by going to Settings > Safari > Clear History and Website Data. This removes stored data that might be causing issues.

6. Uninstall and Reinstall the App: If you’re using the app and are still running into issues, consider uninstalling and then reinstalling it. This can help resolve any corrupted files that may be present.

If you’ve already tried some of these steps and are still encountering an error message, it may be worth checking if there are any account restrictions or limits as mentioned in this UpToDate support guide1.
