Gmail’s account names (you know, the “left” side of your email address) are very forgiving. Read more for more details!
If you registered your Gmail account name like I did, you likely used the form “[email protected]”. Did you know that it doesn’t matter if you used a period or not! “[email protected]” is treated the same as “[email protected]”. In fact, Gmail is not even case sensitive, so “[email protected]” is the same as “[email protected]”! So, not only did you get the email account name you wanted, but you really got more!
Any valid for also works at the login screen too! It surely makes remembering easier!
