Gmail Gets a Fresh Start: Change Your Username Without Losing Your Data
Google is rolling out a feature that lets you change your Gmail username (the part before @gmail.com) without resetting your account data. Your old address remains available as an alias, and all data stays intact, with the option to switch back. Availability is currently limited to the US and India, and you can change your username only once per year (up to four usernames total per account, since you can change it three times after the original). Chromebook users may need to remove and re-add their Google account, and you may need to sign back into some apps after the change.
