Store Username and Password securely for xfreerdp

I am xfreerdp to login to my other pcs. I am storing the connection on bash file, > xfreerdp /multimon /u:{username} /v:{ip:port} /p:{password} > -d:{domain} /f /floatbar /multitransport /network:auto I click on them when I want to connect. But the issue is anyone with access to this machine will get the username and password of my other machines, what is the proper way to store and execute such files. I am relatively new to Linux, so please consider that.
