A Kindle owner recently took to Reddit to lament about something many longtime users have discovered the hard way: Amazon no longer lets certain older Kindles register after a reset. The poster had dusted off a legacy e-reader, only to meet a dead end at the sign-in screen. This experience is, unfortunately, a scenario that’s becoming more common as Amazon tightens authentication requirements on aging hardware.
However, the thread didn’t stay gloomy for long. u/InfiniteAftertime jumped in with a workaround they’d spotted on MobileRead, where enthusiasts have been comparing notes on the same problem. It turns out a quirk in Amazon’s two-factor authentication system can reopen the registration pathway for older Kindles that Amazon appears to have closed.
