SSH keys cannot be modified or updated. To change the keys, remove and add them again.
To delete the SSH key from the app configuration, click Actions ➜ Delete.
If the key is deleted, all repository references will also be removed. Repositories that don’t have the key associated to them will use the common keys by default.
