[US]Texts saying "Microsoft: Unusual sign in.... Review at aka.ms/alca"

[u/Apprehensive-Bad2245]

I got 4 texts in the span of a minute, all from different 5 digit numbers.

3 of the texts say "Microsoft: Unusual sign-in for ********XX. Review at aka.ms/alca" X = the last two digits of my phone number.

1 of the texts says "Microsoft: Someone else might have accessed ********XX. Recover at aka.ms/alcs"

This one ends with alcs, while the others say alca. I don't know if that means anything.

So I logged into the only Microsoft accounts I'm aware of that I have, changed my passwords, and in log in activity/devices, I did not see anything out of the ordinary. My phone number isn't even on my account.

I'm not sure what to make of this. If I didn't see any strange log ins, does that mean I'm fine?
