https://temp-mail.org/en/ That site, bitwarden (self-hosted preferably, but an account with them works too), and you've got all the tools you'll ever want. If you also want to "change" your phone number on the sites you're leaving (that's always a good idea as well), you can try https://quackr.io/ but I'm not sure how good it is. I just found that site, and honestly can't remember what I used for that. All I remember is that it was a free trial of an app for 7 days, and I made sure to finish that before the trial was over. And I'm no sensei, call me Master "4th run of Horizon Zero Dawn" 🤣🤣. Just kidding, I'm just a guy that, like most of is, got tired of all the BS out there these days. I am, though, on my 4th run of that game. Good luck man, you won't regret doing this.
