Google appears to be quietly associating a device's phone number with all signed-in accounts, according to a report from Android Police.
This change suggests that if you have multiple Google profiles active on your smartphone—such as separate personal, work, or secondary accounts—your phone number may now be linked across all of them rather than staying tied strictly to a primary profile.
While cross-account phone number integration can streamline security prompts and account recovery options, it also brings up considerations around privacy and identity separation. Users who intentionally maintain distinct profiles to keep activities isolated may want to review their account settings to see how their information is applied.
Please check Android Police for full details and further analysis of this rollout.
