What it means
Google says Android uses one Trusted places list across settings such as Extend Unlock and Identity Check. Extend Unlock may keep a phone unlocked near a saved place; Identity Check uses the place as context for whether some sensitive actions require extra biometric verification. These are different outcomes from the same approximate location. The place boundary can extend beyond a home or office and is not guaranteed to update instantly.
A real-world example
A user adds a coworking space to make the phone easier to use. The saved place also affects Identity Check's location context, even though strangers share the building. The convenience decision had a broader security consequence.
What to do
Audit saved places after moving or changing jobs. Remove public or obsolete places, review both settings and test behavior away from the area. Use a strong screen lock everywhere.
The distinction that matters
A trusted place is not a trusted person. Google notes that signals can be copied or manipulated and accuracy is around 100 meters. No place should be treated as a replacement for biometrics, account recovery or physically controlling the phone. Adding a nearby office can broaden the area where settings treat the device differently, so the list should be reviewed as a security choice, not merely a convenience preference.
