The users will have to drop everything and scramble to get a stable working login within the next 3 month, not counting the accounts migration that needs to happen. Poor ppl.
Seems to be a successful product with plenty of happy paying customers and no real competitor. Looks like killing a golden egg laying goose. Why would it be shut down so abruptly? The customers at least deserve a reason.
So there are options out there, and 3 months is plenty of time to migrate accounts that need to migrate (I'm sure either of these, and any other companies offering alternatives, would be happy to help anyone making a change).
I'd hate to be the people scrambling to get the 2FA changed
Sounds like some kind of acquisition or merger, with a promise of a future update. In other words, there will be a post-mortem, but they were alerting everyone to the coming death of the product and the services it depends on as soon as possible.
It'd be fine given a year to do this, but three months? Harsh.
