On March 31, 2026, Google announced that users can now change their Gmail username for the first time. A feature millions of people had been waiting for. Sundar Pichai shared the news publicly, and the response was overwhelmingly positive.
But while everyone was celebrating, I was asking a different question.
I raised my first flag: when you change your Gmail username, does mail sent to the old address still reach you? Years of institutions only know you by that old email, banks, universities, services you signed up for years ago and forgot about. The question sounds simple until you realize you can't notify all of them.
My second flag is where it got serious.
For most people, a Gmail address is not just an inbox. It is their identity across the internet. Every time someone tapped "Sign in with Google" instead of creating a password, on Spotify, Canva, Notion, Airbnb, hundreds of other platforms, that Gmail address became the key those platforms used to recognize them. Years of account history, saved data, purchases, preferences, all tied to that one address.
