Does using the same Google Authenticator link Reddit accounts together?

I have one Google Authenticator app on my main phone. I'm thinking about adding 2FA for multiple Reddit accounts to it.


Does Reddit have any way of knowing that those accounts are using the same Google Authenticator app, or is that information completely private?


I'm worried that if one account gets suspended, the others could somehow get linked as well. Has anyone here used the same Authenticator for multiple Reddit accounts? Any issues or is Reddit unable to see that?


I'd appreciate any real-world experience.

You can used it Google Authenticator app for multiple reddit account. There is no any issues and reddit can't see that.

Authenticator itself doesn’t give Reddit any shared ID or anything like that. Reddit just has a separate TOTP secret for each account and checks the 6 digit code when you login, thats it. If accounts get linked it’s gonna be from normal signals like sessions/device/IP/behavior etc, not because the codes sit in the same GA app. I’ve kept multiple accounts in one authenticator for years and never had issue from that specifically.

Oki thx

I don't think so. As far as I know, Reddit can't see that multiple accounts are using the same Google Authenticator app. I've never had any issues from doing that.

Google authenticator iteslf is not something reddit can see or use to link accounts. It just generates codes locally on your device. In practice account linking usually comes more from behavior patterns, IP/device usage and activity rather than 2FA apps. I have used 2FA on multiple accounts without noticing any direct issue from that side.

Reddit can't see which authenticator app you use, so that specific worry is off the table. Google Authenticator is offline TOTP: it makes codes locally from a seed you set once, and it never talks to Reddit or reports what's behind an account. Reusing the same app across all your accounts is invisible to them, so it's not a linkage vector at all. It actually helps, since 2FA cuts down on lockouts and odd login flags.

Where accounts really get tied together is the boring stuff: same IP or subnet, matching device and browser fingerprint, shared cookies or a leftover session, and especially a reused recovery email or phone. Behavior counts too, like identical posting times, the same subreddits, and similar writing style. When one gets suspended and the rest follow, that's the trail, not the codes.

So reuse the Authenticator freely and put your effort where it counts: a clean dedicated IP per account or small group, separate browser profiles and fingerprints, no shared email or recovery, and varied human behavior.
