Depends on the service, but generally speaking, no.
Your program will still call oAuthLogin to get the token (as it always does.)
If the current token is valid, that is returned.
If it has expired then it should get another token automatically (with no user intervention).
After some period of time (depends on the service provider) they will need to manually do the OAuth login again. This could be once a year, or never - it’s completely dependent on the service provider.
