My wife has a google nexus 6. Up until about a week ago, spotify worked fine and she uses it most days (she pays for premium). Now, if she opens spotify, a few seconds later, some sort of weird smart lock messages pops up, and closes spotify app down.
We tried rebooting the phone, didnt help.
We found several posts with the same issue, but none had replies.
Solved! Go to Solution.
Try in this order,
Go to settings-google-Smart lock for password
Disable auto sign in
Go on web and change password
Log in on app
Re-enable smart lock
If that doesn't work try signing out of your Google account maybe?
I had the same problem. Here is how I resoloved it:
1. Go to https://passwords.google.com/
2. In the search box look for Spotify.
3. Press the Delete buttorn.
4. Re open Spotify app, this time you will be able to ener your password
