If a user has forgotten his password, he can obtain a new password by the following procedure. As it is not 100% guaranteed that still the same person is using the system, the access to earlier messages is deleted and the participants of the system are warned to re-validate their trusted relations.

Forgot password

1. Type your PrivaSphere user id, i.e. your eMail address, in the User ID field of the login screen. Click on the 'Forgot password' - button to start the procedure.

2. Choose a new password and enter in the 'choose password' field. Retype the new password and submit your new password to the system.

3. You will receive a mail with the subject 'forgot password' to re-activate your account. Follow the link on this mail and enter the new password.

What happens, if the wrong password is entered too many times? If you have entered a wrong password three times, your account will be temporarily locked. After 24 hours you can try another three times. After the third time of three wrong attempts your account will be locked and PrivaSphere support needs to be contacted. With a security question you have given when registering, you can prove to the support that you are the authorized person. Support can unlock then your account. This procedure discourages password guessing attacks.

Customers report that they find a useful aid to prevent the problem to occur.
