Button "Show password" not available in SecureLogin Manager

Hello,

i'm struggling with the update of an SL 8.7 Application: i change the password but it seems to ignore the new setting. I'd like to check which is the registered password but in SecureLogin Manager the button is blocked (see attachment) even if i'm a privileged user. Is there a way to check the password? May i change any preference?

Thank you in advance

Stefano
