+Changing your attestation key
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+If you change your attestation key without changing your email address (e.g.
+switch from a ``patatt`` generated key to a PGP key or change your PGP keys),
+your previous authorization will stop working. Trying to reauthorize will also
+result in an error as changing the attestation key is `currently unsupported

+Instead, you can change the key selector to something other than ``default``
+with the following setting::
+
+ [patatt]
+ selector = something
+
+.. note::
+ The selector can be anything besides default or any previously used selector.
+ For example, you could use the creation date of your PGP key.
