Messages and FaceTime repeatedly asking me to log in.

I have the exact description of the problem happening with my Macs. However, it is also happening with my iPad Pro 12.9" 5th Gen. I've updated my iCloud password and deleted the Messages and FaceTime keychain entries, these did not improved or correct the issue.

I'm having he exact same issue. It began this afternoon. In my case it has also affected FaceTime as well. Both asking for sign-in and password AFTER successfully signing in and just as quickly kicks me out only to have to sign in again.

Same issue. ALL my Apple devices are affected. My Apple ID is blocked for iMessage and FaceTime. After 2 hours with Apple support I was finally told I need to request, one device at a time, for activation. Go to getsupport.apple.com. It is a complete pain. One device per day. Wait at least 24 hours for an email.

Hi All, Things got working again. My Mac received messages that new devices now have access to Messages on my Mac etc. also messages that I can WiFi Calling on my Mac, etc. Something at the back end got straightened out and I did little to nothing since first posting yesterday. Anyways, my FaceTime and Messages are working again on my Mac and iPads!!

Just spent an hour on chat with Apple with a similar issue, after Sequoia update to 15.6.1, can't make any calls or video calls on FaceTime. Also have to keep logging back in to both FaceTime and Messages. They said my Apple account has been spam flagged and I need to reactivate it. Have done that now but need to wait 24 hours to see if it's fixed. However, this may not be the issue as I noticed when I opened settings in Messages on my MacOS device that only email addresses were ticked, not my phone numbers. All were ticked on my iPhone. So I'd say before contacting Apple, on your MacOS device open Messages, click Settings, then the "iMessage" tab, and check that your phone number(s) are ticked in the list of recognised account options in case this might fix the issue. I believe iPhone defaults to your phone number for these apps which could explain why there are no issues with iOS devices. Will report back tomorrow with an update.

It's not just 15.6.1

I have the same problem, Messages and FaceTime opening, and then after a few seconds going back to login page]

Happening on 4 different Macs.

15.6.1 2 MacbookAirs

12.7.6 Macbook Pro

11.7.10 27" IMac

SOLVED: Reactivating Apple account fixed the issue for me. My FaceTime and Messages are now working fine after Apple reactivated my account. It didn't even take 24 hours, so just an update to say account reactivation worked for me, hopefully it'll work for you too.

I do think the issue may have stemmed from the email address I use for my Apple account which has been involved in a security leak previously, although I have also gone into Messages and ticked both of my phone numbers now so hopefully this won't happen again.

Well, it was great while it lasted. The issue arises again after a series of "A new Mac has been added access to your Messages..." etc over and over. Launching Messages opens an logon dialog, once logged in for a minute, the app quits and goes back to the Logon dialog.
