The procedure for authenticating a user working on a distributed mode client-server computer system operates by use of a single piece of information to be memorised, called a `password phrase'. This is of a given length and allows a given duration of working on the computer system. The system operates within an OTP type environment (One-Time Password) integrated with a Kerberos system. This process may be used with a trusted terminal, or any other terminal. A method is included whereby the password phrase is re-initialised at the end of the working period to ensure the ability to continue working.
