Fair comment.

But the basic principle still holds.
Try adding a "createUser" line for this user in the persistent snmpd.conf file,
and then restart the agent.  This should then be replaced with an equivalent
"usmUser" line, which will then be used for generating the traps.

See above.

Use 'createUser' in the *persistent* file (/var/net-snmp/snmpd.conf),
and restart the agent (to replace this will a 'usmUser' line)
That then doesn't include the passwords.
