Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
You didn't tell us what kind of account you have in mind, which forces us to make an assumption. I assume you are referring to your Microsoft account.
You can sign in to your Microsoft account as many times as you wish, however, if you sign in with an incorrect or mistyped password too many times, Windows will automatically lock you out for a period of time specified in Group Policy. We don't know what that length of time is, because it's not a standard Windows setting. Whoever setup Windows made that decision.
You could try waiting 30 minutes, and if you're still being locked out, wait another 30 minutes, and so on, until the length of time specified in Group Policy passes. Then you'll be able to sign in again.
