Question: My mac apple ID won't authentic properly with my Imessages
So I have a Mac Mini and I don't have phone access to use with my Mac Messages. And I looked online to see if anyone could help me and I tried the solutions other people were saying to do but it still wouldn't authenticate. And I have used my apple ID with messages on this account before but it stopped working suddenly. I just really want to get into touch with some friends. I can't authenticate it with my phone because I don't have my phone with me and so I really need some help with this situation. If anyone is able to help me please reply to this post. Thank you for your time.
Mac mini, macOS High Sierra (10.13.3), null
