The user must be registered to login to Cerberus Portal. The login procedures are detailed in document A6V12050070 Accounts.

For Siemens employees using a tablet or mobile phone to login, the Siemens Login Service requires a higher security level for mobile authentication since the Smart Card cannot be used.

- The option One-time Password per SMS is unavailable if no mobile number is assigned to the personal account.

- The option One-time Password per E-Mail notifies the supervisor each time causing a delay to authentication.

Recommendation: Use your own account, i.e., an account that is not provided by Siemens, for example: myMailaccount@provider.com.
