Wago plc web login password and username incorrect

i did the set up through putty and changed the password, but when i try to log in on the web UI i am unable to use the root as user name and then the pass word i set up

For same reason in putty you use “root” but for the wbm login it is “admin”

yes, in Putty you have access to
root
admin
(other declared users)

In WBM you mainly only use admin.
