Lucky you! I've run into lot of these apps offering only FB/Google sign in. Or offering mobile number only login. For e.g. I like playing scrabble and Scrabble Go only support FB login so I'm playing only as Guest user for months now.

Mobile number login is even worse! Why do I need to share my mobile number for something where you don't need to have it!

I think a lot of services use mobile number login as a way of bot-limiting; harder to create lots of phony email addresses than phone numbers. But it's still a pain in the butt :(

I think you got this the wrong way around.

Mobile number login is common for apps from China as large number of Internet user there only have a mobile phone, no desktop and no email. Its the only way to verify account.
