I've used 2FA on my PSN account for years, but when it was first made available, it was only through your phone number. However, 2FA via phone is not all that secure and authenticator apps are a much better option. I had not used my PSN account for a few years since I switched to playing games on PC, so I have not logged into PSN for a while now, and never even heard the news that authenticator apps could now be used.
Thanks to this thread, I learned that I could now use my authenticator app (Authy, which I use for all my accounts that offer 2FA) with my PSN account! I've now switched over and if you have not done so or were not aware of this, I recommend you switch over too!
See here for enabling 2FA for PSN with an authenticator app:
My recommended authenticator app of choice is Authy. Unlike Google Authenticator, it offers cloud backups and has a desktop app. Authy can be used wherever Google Authenticator can be used, even with your Google Account itself!
Also, if you want to be even more secure (and not just with PSN but with all your accounts), use Authy in conjunction with a password manager like Bitwarden or 1password!
