This almost happened to me 4-5 years ago. I don’t recall every detail but right around the time I was deep into a new job interview process, Google Pay decided it needed to verify my identity. It may have been triggered by one of my cards expiring but I don’t think I had ever used the service to actually pay for anything at that point and just had a card saved. Anyhow, I was almost immediately locked out of my primary email account as well and got delayed in sending documents to the potential employer and had to explain that I got locked out of gmail. Unfortunately, I didn’t learn my lesson and still use that gmail account as my primary email but I did at least open alternative accounts on other cloud providers.
