Article discussing the push for passkeys as an alternative to passwords, including numerous problems associated with passkeys like big companies agenda, complicated proprietary implementations, vendor lock-in requirements and dependency on smartphones, dubious value for ordinary users, and misplaced purpose and value, hype and security, lax IT practices and constant private data leaks, psychological reasons why modern Web and email are interactive and phishing-prone due to profit-driven design, wrongness of clickable links, practice of information-only communication, severe implications for privacy and freedom in so-called modern solutions, some other observations, and more
You seem to be falling for what the author was writing about. Only because you could technically try to use keepassxc to store passkeys, that does not mean that it will work. You see passkeys were build in a way the service you’re trying to login to can decide if they accept your keepassxc for passkey storage or not. It looks like you are in control when you are actually not.
So, same as passwords then. The service can determine what they accept as a password. And if they’re being assholes about it you can decide to go elsewhere.
And what password manager you use, I think was the poster’s point.
There is indeed a big difference between requiring a specific password vs. requiring a specific device or software to be able to use the service. Keep in mind that big tech can very conveniently leverage this technology to lock you in. For example think about Apple, Google and Microsoft requiring you to use passkeys, and then later require you to use your certified phone and app. Most people will not be able to “go elsewhere”.
