Most of the time when I copy a client secret from the web interface in the developer preview sandbox it prepends the string
Hide to the client secret.
A large number of developers will be pasting this secret into an obscured text field (so as to not show it on the screen again). So they won’t even notice it until their application breaks. It will be difficult for them to figure it out since their client secret should be encrypted in storage.
You probably shouldn’t show the client secret on the screen anyway. The best option would be to have a button to put it straight into the clipboard.
I tried to send a support request to help the Okta developers for this but it’s very difficult to sign up to support and I have not received an email saying I was accepted yet. Hopefully somebody will see this here. ¯\_(ツ)_/¯
