Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hi kerry buchecker,
I understand how frustrating this can be, especially when you're trying to complete important documents and the password field is not accepting any input. Based on your description, it would be helpful to first determine whether this is a sign-in prompt issue or an input/display issue within the application itself.
As a quick check, please try:
- Close the affected Microsoft application completely and reopen it.
- Try signing in to Microsoft account from a web browser to confirm the account itself is accessible.
- Let us know where the password prompt appears (Word, Excel, Outlook, OneDrive, Microsoft 365 activation, or elsewhere).
If possible, please share a screenshot of the prompt with any personal information removed. This can help identify whether the field is genuinely locked or if another window or setting is preventing input.
Hopefully we can narrow down the cause with a bit more information and get you back to your documents as quickly as possible. I look forward to your update.
