Credential Store in encrypted form in ServiceNow

If you have 'Discovery' enabled in your ServiceNow instance then you can save credentials in an encrypted form inside discovery credentials.
These credentials can be used to access a 3rd party tool through ServiceNow features such as orchestration/Discovery or can be used for internal use.

Use case:

Consider you have to access a 3rd party tool through ServiceNow (with or without using orchestration). Access to this 3rd party tool require userID and password which you have to store in a encrypted form and can be decrypted whenever required.

This blog will help you in how to store and access the credential using discovery credentials feature.
