You can use any combination of dots in your Gmail address, and the email still goes to the same place (i.e. [email protected], [email protected], [email protected] are all the same). Turns out you can also log into your Google account with any dot combination.
If your Google account username/Gmail login is jane.smith, you can also login as janesmith, or ja.ne.smith, or any combination you prefer. If you're typing manually, the dot-free version seems like a good pick. In addition in being able to login without the dots, Google blog Google Operating System writes that, as we highlighted in the past:
It's important to keep in mind that Gmail ignores the dots from your username when receiving a message, so you'll get all the messages sent to [email protected], [email protected], [email protected] and other similar addresses. The requirement to enter the same username you used when you created the Gmail account might have helped you keep the account secure, but it was really annoying.
The change is just for Gmail users only; Google Apps users for domains do require fidelity to the dots.
