They work by giving you a random email address that is available for a short time (ex. 10min) and an inbox for any messages you recieve during that time (ex. an email verification message from a Lemmy server)
I didn’t want to recommend a specific one, however Googling “temporary email” should give you several options to choose from.
Just don’t ever forget your password to said Lemmy instance because you won’t be able to reset it.
Also be aware that sometimes the decision to reset the password is not done on your side. Sometimes due to attacks or similar website owners might decide a forced reset and that might require the email.
I had a scare when i went to setup 2fa, I guess i only copied the last digits of the link thinking all I needed were the numbers and then I couldnt sign in, luckily I still had an open tab with my account signed in and was able to redo the 2fa before being completely signed out, with no email on the account I would have had to start over
Are there really people out there not using a password manager in current year?
Many people don’t like putting their eggs in one basket. Which I get. But imo as long as you’re properly securing everything as well as you can, most decent passwords managers are trustworthy enough.
When I first set up my password DB I forgot my master password. Fortunately that didn’t happen on my second. I still have the locked first db.
I’m personally deeply skeptical, even if it’s from one of the most secure companies I would have a heart attack if I hear it’s hacked.
I personally just use pen and paper, two copies, and try to do variations or new passwords for things I care about and then one common password for useless things with no credit card info.
