Today is a sad day. After 14 years, my physical Authenticator (purchased when they first came out) finally told me it was running low on batteries.
So I have removed it from my account, and downloaded the app on my iPhone and put that on my account.
The entire process was quick and easy, and it was a nice touch that the notification to approve came up on my watch, so I don’t have to scramble around the house trying to remember where I left me phone (probably in the car).
I’ve got one too, dreading the day the battery will die but I always hoped somehow you could pry it open and replace the battery. A quick Google search tells me this apparently isn’t possible.

edit: it seems that if can make your way through the casing, which is really hard, you cán replace the battery.
