Questions
Can Pagerless roll back Fly.io automatically?
Yes, if your rules set undo to alone. By default it asks first, and approving an undo needs your passkey (Face ID or Touch ID). It then moves Machines back to the previous image.
Does Pagerless need admin access to Fly.io?
It needs a Fly deploy token. It is stored encrypted and used only for the fixes listed above. You can skip it: alerts work without it.
