[Android Apps and Games] GalaxyA325G:
Thank you for bringing up that question of the potential loss of privacy inherent in the OTP apps because all this is foisted upon me, a typical user, simply because of what Google alone did, after May 30th, 2022, for authentication via 3rd-party MUAs such as Fair Email.

Don't all those OTP apps REQUIRE Internet tracking information?

Please bear in mind I'm a typical clueless user, so it goes without saying that I know almost nothing about OTP apps. This is simply because I've never needed OTP apps until this unilateral change by Google after May 30th.

So I may be wrong... (and if I am wrong, please just let me know that I am wrong as I would love it if the OTP apps did NOT require a mothership tracking account on their servers or other Internet tracking information akin to what's asked for in 2SV/2FV after all).

Backing up to the first time OTP was suggested, I am an average user, and as such, I had never heard of OTP apps until Marcel kindly suggested them to me earlier in this thread when the Fair Email app was creating the Android on-device accounts (because Google was forcing him to authenticate OAUth2 that way).

The instant Marcel kindly suggested the free OTP apps, I tried all the free ones that I could find using the Aurora Store search engine (as I don't have the Google Play Store app enabled on my phone) - and - much to my chagrin - every free OTP app that I tried seemed to REQUIRE a mothership tracking account on their servers or other tracking information akin to 2SV/2FA (as I recall)...

That's anathema (if it's true).

It's just trading one way to lose privacy with another.

That's not progress.

The entire point of OAUth2 via the web is to NOT hand away our privacy via 2FA/2SV or login account or by any other Internet tracking information, right?

To bolster my defense in that I was asking for advice, this is what I wrote in the thread I opened on the subject at the time Marcel had suggested OTP apps (bearing in mind I had to look up what the words OTP even stood for - and then I had to figure out what specific OTP apps Marcel was suggesting at the time)...

Do the OTP apps require tracking information or not?

Maybe I'm wrong as I only tried those OTP apps above because Marcel kindly had suggested them - which - I may need to repeat - is the first time I had ever heard of the functionality - so if I'm wrong in my conclusions - just let me know that I'm wrong.

As I recall at the time I tried them (a few weeks ago), EVERY ONE required a mothership tracking account on an Internet server or some other "second something" which surrenders my privacy (which is something I will never settle for).

Bear in mind personal privacy is like personal hygiene in that it's a thousand little things tied together in a chain of events, where one of those thousand little things in the chain of events is not logging into any Internet servers that I don't have to log into (email is, unfortunately, one horrible but necessary exception) and not handing out a "second something" that always has to be with you forever.

Am I wrong?

None of my apps, as far as I can recall, require a log in to a mothership server, and I must have over 750 apps installed on my main phone because I test out apps all the time.

BTW, we have to be careful that we don't stray too far off of the Fair Email purpose of this thread, so maybe this should be taken up here...

What are all the available 2FA/2SV/MFA/MSV options for 3rd-party mail programs to log into Google mail servers after May 30th 2022
