authentication

[tanya and steven atkinson <srandtkatkinson optusnet com au>]

Hi

My daughter has misplaced her authentication password or has forgotten
it or both. Anyway we tried to load some software (Skype) onto her
computer and without the authentication we could not do it. is there any
way one can find out what it is or cancel and generate a new one.
Yours sincerel
