OSM's OAuth 1.0a is in the process of being deprecated, as discussed at openstreetmap/operations#867.
No timeline has been set, but we do not expect to shut off OAuth 1.0a this year. It would be good to move to OAuth 2.0 well before this time.
Thank you for making us aware and sorry for not replying until now. We really appreciate that you gave us a heads up and since then we have been planning to fix it.
Today we made a release with oAuth2 integration instead.
The site isn't actively developed at the moment. But we do try our best to maintain it. We also have quite a long list of things we want to do and we hope to be able to spend the time we want to the coming year.
