We encourage creating an email for specific purposes to not sharing concerns across identies. We suggest:
In proton mail, click on your initials in the upper right corner
Click on “Settings”
Click “Recovery” on the left sidebar
Scroll to “Recovery phone number”
Go back to AnonySMS, wait a few seconds, and refresh the page
Many emails require some kind of verification or backup email with different restrictions. Proton is flexible enough to allow this form of verification through. ↩
There are many online sites to grab free phone numbers and you’re welcome to find one that works for you. We’ve found this one to be reliable and easily lets you see the text messages that come through. ↩
