You can change the user pin used for authentication when the keystore is opened.

Refer to the openCryptoki project documentation for instructions on how to do this.

You must then either reopen the keystore with the following SQL or restart the database server.

SELECT pgx_open_keystore('newUserpin');

As soon as you change the user pin, back up the entire opencryptoki token directory of the slot you assigned to Fujitsu Enterprise Postgres.
