Hacked - Google account constantly generating new Windows devices/passkeys
My fiancé has been hacked or heavily targeted on his Gmail and we are completely losing our minds trying to figure out what is real and what isn’t.
First and foremost: yesterday he received an email saying his Google account was compromised, followed shortly after by a phone call from someone claiming to be Google support. We now know it was a scammer impersonating Google, but at the time he didn’t know. He owns multiple businesses and gets a ton of calls daily, so nothing immediately seemed off and it looked/sounded legitimate.
Fastf orward to this morning, someone also attempted to access his bank account and reset his password, and someone later called a crypto company associated with him and attempted a password reset there too (thankfully they stopped it).
Since then, for the past half day straight, his Google account keeps showing new Windows sessions/passkeys and devices in locations like Ohio, Idaho, Nebraska, etc. — even though he only uses Mac + iPhone and owns no Windows devices at all.
The weird part:
- We sign out/remove one → another immediately appears
- One disappears and another replaces it
- Fresh timestamps keep generating
- They say
- "Created automatically by Android"
We have already:
- Changed the password multiple times
- Signed out of all devices
- Reset 2-Step Verification
- Removed passkeys/devices repeatedly
- Checked recovery info
- Cleared browser cache/data
- Spent 2 hours with Geek Squad at Best Buy (they were completely stumped)
We've since created a new Google account and changed the email on all his secure banking sites.
Also incredibly frustrating: Google has been no help whatsoever. After several calls, we were basically told to just post in the Gmail Community Help Center, which feels insane given the situation.
At this point we’re trying to figure out: real compromise, weird Google/Android passkey sync issue, or something else entirely?
Has anyone seen "Created automatically by Android" repeatedly generate Windows devices/passkeys before? Or are scammers just getting that much better with AI automations/account takeovers?
Any insight would be appreciated because we are absolutely exhausted.
