If it is of no use, it has no value. If it has no value it is worthless. It would implement it in a heartbeat if my bank, brokerage firm, investment accounts, etc., etc., utilized it, but none do. Even though in theory it represents a significant step in securing logins the lack of implementation.Your use of the word worthless is what I was taking exception to. SQRL may not be your cup of tea, but it is far from worthless. Anyway... my greater point was that there is no point acting entitled... no one is entitled to SpinRite other than for the grace of @Steve's kindness to continue to work on it for free. (Much as he worked on SQRL for free.)
I use BitWarden, because it provides a service, securing and managing my passwords/logins, thus it has value. To implement SQRL as a one-off solely to log into this forum is a little excessive.
SQRL would be my "cup of tea", if it had value. Aside from this forum and probably the SQRL forum, where is it actually implemented?
Today, SR is worthless to me. It had value at one time because it worked, but no longer works on anything I own, and none if it is that high end or exotic. Off the shelf laptop with i5 and 500G drive, nope. Referb tower with 1T drive, nope.
As for Steve working on SR for "free", I believe that is a commitment he made early on in his development and enhancements to SR. The link to buy SR still states "Any software purchased or upgraded online can be replaced or updated to its latest version at any time." Generous of Steve, but something we also paid for.
