Maybe spotify downloaded a data breach and ran it against their db to force better password practices?
My user/default password plaintext combo from when I was 15 was leaked in some EA hack a long time ago. That caused such a headache that I stopped using the same thing everywhere except free services. This initially included spotify. Then I upgraded to premium, and about a month later someone was trying to kick me out of my account (listening from their device) and kept playing weird music. Now everything has its own password. EVERYTHING.
