Sign In Error in Microsoft Word

Dear Sir/Madam,

I have been having issues with my Word account. I needed to update my version of Word a few weeks ago, and it worked successfully. However, now, every time I open a Word document I have to sign in to my account, and it doesn't seem to save my information. Normally, in the past, I only had to sign in once when updating Word and then it saved my information for one year, until the next update. I have a student account, where I am able to access Word through my university for free. Even though my Word works in general, it is very tiring to have to enter my profile information anew each time I open the Word App on my laptop. Could you please tell me what the issue is and how I might be able to fix it?

Thanks a lot in advance!

Best wishes,

Johanna März

hi Hendrix-C,

thank you so much for your help!

For some reason my Word started working normally again, without me having to sign in these past few days, even though I didn't do the steps you suggested (because it wasn't even necessary anymore). I don't know why it works again, but I hope it stays that way!

Thanks again any way!

Best wishes,

Johanna

    Hi @Johanna März,

    Based on your sharing, this is highly a Keychain / Office credential cache issue. Office for Mac can repeatedly ask you to sign in when it cannot properly access or save credentials in the macOS Keychain. Therefore, in this case, I highly recommend restoring Office Keychain access first:

    • First, quit all Microsoft 365 apps
    • Press Command + Space to open Spotlight > search for Keychain Access and open it.
    • In the top-left area, select the "login" keychain.
    • From the menu bar, select File > Lock Keychain “login”.
    • Open Word again. When macOS asks for permission to access the Keychain, enter your Mac administrator password and choose OK.
    • If Word asks you to sign in, sign in with the university/student Microsoft 365 account that has the Word license.
    • After Word opens successfully, quit Word completely, then open it again to check whether it stays signed in.

    Please try the steps and let me know if it works. If not, please notify me and we can work together to solve the situation.

    If you have any questions or need any further clarification, please leave a comment here and I will be happy to continue to help you.  

    Thank you for your patience and understanding. I'm looking forward to your reply.
