I am planning to add a basic auth middleware to traefik in k8s and as such I am following the guide at https://doc.traefik.io/traefik/middlewares/basicauth/. In here the example secret for storing the username:password is as such
apiVersion: v1 kind: Secret metadata: name: authsecret namespace: default data: users: |2 dGVzdDokYXByMSRINnVza2trVyRJZ1hMUDZld1RyU3VCa1RycUU4d2ovCnRlc3QyOiRhcHIxJGQ5 aHI5SEJCJDRIeHdnVWlyM0hQNEVzZ2dQL1FObzAK
I can get the base64 encoded part and I can see that 2 usernames and passwords are defined. But what is the "2" for?
