Originally I loved this option through Spotify, where you’re able to simply verify through your email to login rather than use your password. Especially since I’m always forgetting them to random subscription services. However, my account was recently hacked and I used this option after they had reset my password. I was able to get into my account, but then had no idea that it was hacked - Thinking I just forgot another password. They then had access for multiple months, changing the subscription type, the email and password on file until I finally found out when I had to log in on a new phone. If I hadn’t gotten a new phone, this could’ve gone on forever without my knowing. Had the same issue with Netflix, but I had to immediately reset the password because there’s no other option - This prevented them from having access there for more than a day. Plus Netflix logged me out everywhere, so it was pretty clear there was an issue (Spotify doesn’t do this either). Spotify was super great, resolved (and refunded!) back everything, but eliminating this feature would’ve saved me (and them) time and money. Just a thought!
