I use m.kuku.lu, but if you plan to have more permanent account on there, like me, there’s one problem it has. It NEVER invalidates old cookie tokens, even after a password change. This means if you get compromised or forget to logout on someone else’s computer, there’s nothing you can do about it.

Edit: Forget it, they recently added “Log out on all devices” button.

Edit 2: At the bottom of https://aquapal.net/ it also says they use solar power, if you care about that.

Mailbox.org ?

Create your account through old.reddit.com; when it asks you for an email, simply press “next”. And, if you need an e-mail provider for some other reason, protonmail.com doesn’t ask you for your phone number.

That said do you really need a reddit account?

tutanota didn’t require a phone number, last I checked

Doesn’t Firefox now include an email spoofer by default?

It keeps popping up to ask me on singup screens, and the one time I tried it seems to just provide a valid email and a forwarding service for TFA. I don’t know if it’ll work with Reddit or how effective the service is, though.

I have heard of proton mail but haven’t tried it

Protonmail?

Try Firefox relay. It can set you up with a randomly generated email address that will forward to your regular email.

My guy, reddit doesn’t even care if your email is valid. Just use some keyboard spam like aocjd@sjd.aa, it will accept it
