Unable to login to Gmail account on iPhone

SOLUTION:

if both the "send text" or "tap on device" options are greyed out and you cannot log into Gmail

due to a double-authentification requirement...

- go ahead and choose the option that is scary and says "may take 3-5 days"

-- then the text message option will finally work. It will fix it immediately.

If you can't sign in to your Google Account in Gmail, Google Drive, Google Play, ... You know your username and password, but you can't sign in.

Can't sign in to your Google Account

Gmail is a Google service and application.

login issues to Google’s website, services or applications would need to be addressed by Google, not Apple or Spectrum.
