The Second Password expiration parameter should be defined in the System Config Manager. The TTL day parameter defines the maximum use time allowed for the Second Password.

1. Navigate t&#x6F;**&#x20;Administration** > **System Config Man**.
2. Add the **aioc.second.password.ttl** parameter with a value (in days).

:::hint{type="info"}
If this value is set to "-1" and “0”, the SSH Key will never expire. The TTL value can be set between -1 and 10000.
