Here's how Android 15 blocks thieves from bypassing factory reset protection - eviltoast
Factory reset protection is getting several key upgrades in Android 15 to make it harder to bypass.

This article goes into more detail about how these new measures will actually work compared to the blog post earlier this year from Google. Namely:

  1. Enabling the OEM unlocking setting will no longer prevent FRP from activating.
  2. Bypassing the setup wizard will no longer deactivate FRP. FRP restrictions will apply until you verify ownership of the device by signing in.
  3. Adding a new Google account is blocked.
  4. Setting a lock screen PIN or password is blocked.
  5. Installing new apps is blocked.

    I think you would be fine. You’re only restricted if you log into the vanilla ROM, do some stuff, and later if you want to use the vanilla ROM again you’ll be required to login to the account you used last on the vanilla ROM to make it happy with the device.

    I don’t expect custom ROMs will have any compatibility with this feature. I believe they would bypass it entirely.
