It would be an added security feature to have the option of registering a secondary e-mail address to your account. Should you lose access to your registered e-mail account, there would be a fallback e-mail for access. This is especially important when using two-step login.

I would like that most online services provided this option as a default. Considering that the frequency of episodes where Google locks people out of their accounts appears to be increasing due to the automatic flagging system they use (based on news covering these issues in the last year at least), and that it seems almost impossible to recover your account once this happens, a secondary e-mail would work around such issues.

The most recent case is the Terraria developer, which is locked out of his Google account for three weeks already and has received zero help from Google support: https://arstechnica.com/gadgets/2021/02/terraria-developer-cancels-google-stadia-port-after-youtube-account-ban/

If you've lost access to your email account I'd think you have bigger problems than your game collection. On a side note, isn't Stadia basically on its deathbed? I imagine that's would factor into their decision to cancel a Stadia port.

Never heard of somebody being banned from GOG, but it could be a good idea.

Indeed... I'd be more worried about things like bank accounts, amazon, friends list, spoofing, duping family/friends for money, it would be quite an annoyance.

Then again if the service disappears (vs say getting hacked) then that is a little less a worry and a lot more getting locked out of accounts i hadn't touched in a while.

Not yet -- they just scuttled their in-house gamedev studio, AFAIK.
Whether the service itself will still be around two or three years from now, however, is an open question.

don't most Email providers have secondary 2 step Email accounts?

yahoo have when i need to recover the password it sends a code to the other Email
also link that Email to your first Email account (so you get entanglement)

you have always access to one of the 2. because you link the other to a phone or device

then remake your password with this.

choose 512 password Length
copy that password

you set for live nobody can hack a 512 digit fake semi random password.
unless you have a QC.... but don't worry people that have can't really use them yet.

why? you lose your acc you would have to rebuy the products , more money for them

Not if you've been exercising your DRM-free rights you don't. What's the point in buying DRM-free if you're not going to keep the installers?

Moral of the story... Don't use services from big tech companies that you actually rely on as your primary or only source...

A long time regular forum user (many people would know this account, known for many non-sequitur posts, but usually light-heartedly) was briefly banned from all of GOG (he said). It was revised after a couple of weeks to only no-forums, but, reportedly even during that interim, even his library did go away (which *ahem* should never happen in any way).

I was just thinking about this. I'd welcome an additional recovery option, whether it's via a second e-mail address or text message. It's in the community wishlist, if you want to vote for it: Multiple email address for two-factor authentication

Years ago, my e-mail provider at the time decided I was trying to log in from "an unknown device" and simply knowing my password wasn't good enough. It wouldn't accept the answers to the security questions (maybe I was missing some punctuation, who knows) and the recovery e-mail address was from a provider that no longer existed. So I never regained access to that account and it was presumably purged for inactivity after some time.

I no longer use that provider and my e-mail recovery options are up-to-date. I don't have anything crucial stored in my e-mail account, but in contrast, losing access to things I bought would be devastating. "Just download the offline installers" isn't a solution when you need the account for online-only features, updates, support, multiplayer, and any sort of user interaction and game progress tracking.

Oh shit, that terrible! This user regain access to their games after that??? Now I'm thinking that the two email verification sounds better than ever...
