I am unable to access Fortinet free training anymore

hi,

have a look at https://helpdesk.training.fortinet.com/support/solutions/articles/73000524089-how-do-i-log-in-to-the-fortinet-training-institute-portal- 

Were you able to resolve this? 

A week or 2 ago Fortinet merged all different login options (Support/Training/whatever) into a single FortiCloud login. I had to reset password in FortiCloud to access Training, this password now works for training.fortinet.com, support.fortinet.com etc. - have you tried Forgot the password procedure?
