Asked to sign in again while working
A sign-in can end after a period of inactivity, when you log out in another tab, or when the password is reset. The editor opens sign-in over your existing map. Keep that page open: closing or refreshing the whole page can discard work you have not saved.
Sign back in over the map
Enter the account email and its current password, then choose Continue to my maps. The map stays behind the box. If the password was changed on another device, use the replacement. Closing the sign-in box leaves the map visible but does not restore account access.
Repeat the save or download
When You are signed in again appears, dismiss the message and repeat the save or download you were making. The interrupted action is not automatically repeated. Check that the save reaches My saved maps, or that the expected file downloads, before leaving.
Your sign-in was updated in another tab
The tool has refreshed its sign-in information. Read and dismiss the message, then repeat your save or download. Keep the current map open. If it asks for the password again, sign in and try the action once more.
How long a sign-in lasts
A sign-in lasts up to 12 hours and has a two-hour inactivity limit. A password reset also ends older sessions on other devices. These limits apply to signing in, not to how long a saved map is kept.
Moving to My saved maps
An active sign-in is carried into the saved-map manager; you should not have to enter the password for each visit. A direct bookmark can ask you to sign in first, then return you to the permitted page. If the account cannot access a map, check that it belongs to the email you used.
Finish with Log out on a shared computer
Open the account menu and choose Log out. Save & Logout saves first; Logout Without Saving leaves unsaved changes behind; Cancel keeps you in the editor. Do not assume that merely closing a tab signs you out.
What this looks like
Real GBMaps dialogs with example account details. Choose View larger to read a message clearly.
The confirmation explains that the interrupted save or download still needs to be repeated.
