a sign in from St. Louis

Sign-in locations are based on the IP address used when the account was accessed, not the exact physical address. Networks (especially mobile or some internet providers) can route traffic through different cities or states, so a sign-in from the correct device and app can appear as coming from a place like St. Louis even if the actual location is different.

To check whether the activity is legitimate:

1. Go to the My Account page for the work or school account and open Recent activity.
2. Expand the St. Louis sign-in entry and review:
   • Device/operating system
   • Browser or app used
   • Date and time
3. If all details match normal usage (device, app, approximate time), it is likely just network routing causing the St. Louis location.
4. If anything looks unfamiliar (unknown device, app, or time) or if the sign-in is clearly not from you:
   • Immediately change the account password.
   • Go to the Security info page and update security settings (for example, add or verify phone/email and enable two-step verification where available).

Location data can be approximate and sometimes inaccurate, so always verify the device, browser, and app details in addition to the city shown.
