Awesome-loginless: internet services that don't require registrations
I added try without signing up in my app[1]. Yet some users still use disposable mails, so there is that.<p>From a app developer perspective, it is definitely a downside when people use your app without email. You have no longer way to contact them for feedback or updating them on new releases. But it definitely filters genuine users. And also, people are more likely to checkout your app when you provide guest sign on.<p>I remember reading that Paulo Coelho distributed free copies of his books[2], so that people actually read what he wrote. Same with an early stage app, you should allow people to use what you have built as frictionlessly as possible, IMHO.<p>[1]: <a href="https://primerlabs.io" rel="nofollow">https://primerlabs.io</a><p>[2]:  <a href="https://www.openculture.com/2011/09/how_paulo_coelho_started_pirating_his_own_books.html" rel="nofollow">https://www.openculture.com/2011/09/how_paulo_coelho_started...</a>
