Not everyone can use Briar because of that. Not even Matrix does it in most instances. If practically no one goes p2p approach, how is it an argument? You don’t even provide a solution so why bring attention to a ‘problem’ in the first place?
Every way is a security risk in itself. For example if my home burns down I lose x% of the ways. y% can potentially break. z% can potentially be lost to my stupidity. What if I get in a car accident and hit my head and get amnesia and forget a mandatory password: for these cases there are different retrieval strategies, but obviously are ‘stressful’ to set up to stay relatively secure. What can I say, these are the thoughts I have about this topic.
FIDO2 is great. Only thing I am scared of is losing it/them. So a backup access becomes the issue IMHO.
AFAIK you can’t be in two profiles at once (in GOS). I would use a 2nd device that I keep online, easy solution?
