The second warning line for nitrokey on the security keys page Security Keys - Privacy Guides needs correction.
Resetting the OpenPGP interface on a Nitrokey will also make the password database inaccessible.
This should be changed to :
Resetting the OpenPGP interface on a Nitrokey pro2 will also make the password database inaccessible .This limitatoin does not apply to the newer NItrokey3 keys
i have tested this , opengpg reset does not reset all the passwords in nitrokey 3 version.Also refer specific guide for Nitrokey 3 reset which does not mention this limitation too.
