I've had the same email from Slack. My phone is 5½ years old. It works fine, so I don't want to replace it, but even more than that it's small — 148x73mm. There are no other decent Android phones of a similar size! (I have signed up at https://smallandroidphone.com/ https://smallandroidphone.com/). But back to the point, in Denmark the national identity system relies on either a smartphone app or a key fob for authentication — it's needed for online banking login, online credit/debit card purchases, viewing my medical records, etc. The app supposedly might work, or might be made to work on a custom OS, but from reading around Reddit it looks like a continual hassle to keep it working. I also don't much fancy adding a large fob to my keychain, especially as unlike in the app the number on the fob isn't protected by a fingerprint or PIN. (I'm on call sometimes, and we use Slack to coordinate, so I may end up with no choice. Whether work pay for the new phone or myself is irrelevant, it's the environmental footprint and size I care about.)
