Having trouble with the Twitter for iPhone app? Below is a complete list of troubleshooting techniques:

Remove your account from the app and log back in
Uninstall and reinstall the app
Try clearing your phone's cache
Check that your time zone settings are set to update automatically

Remove your account from the app and log back in

If clearing your phone's cache or turning your phone off and then on again didn't work, you should try removing and then re-adding your account to the app. This is essentially the same thing as logging out and back in again, but since there is not "log out" option on the app, you'll need to remove the account from the app entirely and then sign back in.

Note: The instructions for removing an account from the app are different for iOS4 and iOS5 (and higher). If you don't know which OS version your phone is running, you can check by going to your iPhone's Settings > General > About > Version.

To remove your account from the Twitter for iPhone app:

  1. Go to your phone's System Settings.
  2. Tap on Twitter.
  3. Tap on the account that needs to be removed.
  4. Select Delete Account.

To add your account back to the app:

  1. Open the Twitter for iPhone app.
  2. Tap Sign in.
  3. Enter your username and password.
  4. Tap Done.

If you've forgotten your account's password, follow the troubleshooting steps below to recover it.

How to send a password reset from your mobile device:

  1. If you're using a mobile device to access Twitter, you can send yourself a password reset via Twitter for Android, Twitter for iPhone, or mobile.twitter.com.
  2. On the welcome page, select Sign in and then Forgot password?
  3. Enter the email address or username that you are trying to request a password reset for. If you have a phone number associated with the account, you can choose to receive a reset via SMS. 

For more information about resetting your password, please see this article.

Uninstall and reinstall the app

If above troubleshooting steps didn't resolve your issue, you can try deleting and reinstalling the app on your iPhone.

To uninstall the app:

  1. From your home screen, press and hold your finger on the Twitter for iPhone app icon.
  2. The icon will begin to wobble and an x will appear in the top left corner of the icon. Tap the x.
  3. Your iPhone will ask you to confirm your decision to delete the app. Tap Delete.
  4. The app will disappear from the screen and has been deleted from your phone.

To reinstall the app:

  1. Go to twitter.com/#!/download/iphone and click Download now.
  2. Open the App Store app on your phone and search for Twitter.
  3. Tap Install.

Try clearing your phone's cache

  1. Tap the Settings app icon on your iPhone.
  2. Tap Safari in the list of applications.
  3. Scroll down and select Clear History and/or Clear Cookies and Data
  4. If you've cleared your cache but are still experiencing the issue, try turning your phone off and then on.

Check that your time zone settings are set to update automatically

If you're seeing "Unauthorized" or "Invalid username and Password" when you try to sign in, this is likely caused by incorrect time zone settings or an outdated version of the Twitter client application. Please make sure your Twitter client is up to date with the latest version and that the date, time and timezone settings are set to update automatically.

To check your time zone settings:

  1. Tap the Settings app icon on your iPhone.
  2. Tap General.
  3. Select Date & Time.
  4. Make sure the option to Set Automatically is enabled.
