In the past I’ve recommended sms-activate for easy, quick and low cost phone verification. When you want to log in, they now force you to click on a verification link send by email, meaning you are f’ed if you used a single-use email address.
Are there any alternative options that accept monero and don’t have this restriction?
Ah that’s too bad. Then… you’re locked out, I know that sux. Ideally, you could’ve gotten an anonymous domain of your own, e.g. from Njalla, and then you can have as many new mail addresses as you like, anyting@your.domain. As long as you have that domain, your email addresses will work forever (even though e.g. a hosting company disappears, you can just use another hosting company, by simply editing dns). But obviously, it’s too late…
