Postman Authorization Key Value

[nakulsolanki]

For the following three requests there is a hardcoded header valeu for Authorization key i.e. Basic ZGVtb2NsaWVudDpkZW1vY2xpZW50c2VjcmV0

1. Password Grant
2. Client Credentials Grant
3. Refresh Token

What is this key used for? Can I change it? How?
