I changed my gmail password after suspicious activity was detected. It works fine on my computer but my iphone 5 doesn't recognize my new password ("cannot get mail" message). I've tried changing my phone settings to the new password, but no good.

Hello there dinadinadina,

It sounds like you have modified the password settings for your Gmail account after changing the password. Thats where I would have started too. Next I would restart the device and test it one more time, and then remove and add the account again in Settings:

Get help with Mail on iPhone, iPad, and iPod touch

1. Restart your iOS device.
2. Delete the affected email account from your device.
   1. Tap Settings > Mail, Contacts, Calendars.
   2. Tap the affected email account.
   3. Tap Delete Account.
   4. Add your account again.

Thank you for using Apple Support Communities.

Take care,

Excellent, thank you for the update. Im glad you were able to resolve the issue.

Hi dina (x3).

Can you please provide a url where I can update my Google settings? I'm having the exact same problem you're describing and I can't retrieve mail on my iPhone and desktop. I can get mail from my laptop, which is the device I used to activate 2-step verification after an unauthorized sign-in attempt.

Thanks in advance.

I had the same problem after a suspicious log in, I changed my password.

You just need to create an 'app password' and replace your old password...

Go to: https://support.google.com/accounts/answer/185833

then click on 'How to generate an app password' and follow the instructions.

e.g I went to app passwords, selected Mail - Mac - added the 16 digit code in the password box and it worked!

For my iPhone I did need to delete my account & re-add using the App Password but it re-added all my calendar info, notes etc as they were previously saved on my gmail account.

Hope this helps as I spent ages looking for this answer.
