Well, something like this has actually happened to me with the 2FA, and especially about 3 years ago I had a problem with an exchange where I lost my 2FA and I had to send a very rigorous kyc so that they could give me access, that was something very The truth is tedious, I would not want to go through something like this again, it seems to me that nobody should, and as you say, laziness took possession of me at that moment, but private keys, 2FA attestations should always be kept very well guarded, on flash drives, cds, anything but the cloud, because that is our source of security.
Its a bad idea keeping a copy of your 2FA backup keys on cds or flash drives or any other digital format in a raw text, but if you do, you should always encrypt those with a strong password.
You should do to your 2FA backup key the same you do to your seed phrase or private keys.
It is things like this that we are lazy to do, not because saving them is difficult, but when we consider such things as trivial things. In the end, we ourselves will be in trouble later, if 2FA is lost somewhere. Actually we are very capable of taking care of what we have to take care of, but once again laziness is the main problem in us. I think things like this are not experienced by just one or two people, but many people experience it.
I also experienced loss, but in my seed phrase, but my loss was not due to my laziness, but rather my ignorance at that time.
Well yes, there is no denying it, sometimes laziness makes you make mistakes like that, but if it is good to put all that under an encrypted key and do many things to keep security safe and clear via SHA256 is something that cannot be overcome For this reason I think that the things that are done are enough to always safeguard our most precious data, also when it comes to money security has to be maximum, in the case of how to save I said all those devices because sometimes in If a pc is damaged it is a rpobelma, I have seen many dramas for it.
