NiFi SFTP - How to deal with credential changes every 3 month on the computer that NiFi SFTP going to access ?

[#1]

Hi, 

In NiFi SFTP Processors (GetSFTP, PutSFTP, ListSFTP, FetchSFTP), we are required to input the credential (Username & Password) of the other platform that we are going to access (Computer A access to Computer B)

In situation where other platform (Computer B) have it password changing every 3 month unknowingly and without affecting the automate data flow is there a way that we can handle this situation ?

Thanks
