Thank you for the inquiry!
No, it is not possible to recover the password generated with the genkey from the Telnet session for the Roku channel.
The purpose of the genkey command in the Roku development process is to generate a new private key that is used to sign your channel's code. This private key is required to update your channel in the future. The password is used to protect this private key and prevent unauthorized access.
Once you generate the password for the private key, it is not stored anywhere in Roku's system or on your computer. Therefore, if you forget the password, you will not be able to recover it.
It is important to keep a secure record of the password and the private key file because losing either of them can prevent you from updating your channel in the future.
