If you are on iOS, I recommend using the following:
It’s open-source and recommended by PrivacyGuides.
I’m on Android, where that’s also an option I believe, but I’m using Aegis.
Bitwarden also came out with an open-source MFA app, though it’s a bit new so I’d recommend waiting to see what folks say about it.
Raivo uses to be a good (and the only decent) choice for iOS but I believe it was acquired by an insidious company.
Former USAF JAG here (lawyer). I was always a tech geek, undergrad major was in MIS actually, but I didn’t enjoy coding. Always ran Plex on the side, built my own computers, etc. Grew up with my Dad using Linux everywhere (I found this annoying as I just wanted to play games on Windows).
I didn’t enjoy law (surprise!). I was disillusioned with the criminal justice system too. Quit the law in 2020. Then suddenly had quality time by global happenstance to rethink my life path.
I work in IT now. Restarted at the bottom of a new career but I’m in deep nerd territory now - Proxmox servers, Home Assistant, networks with VLANs, OPNsense router, 22U server rack, Linux as my daily driver, etc.
Much happier now.
