On 1Password 7 for Windows:
In the item list, the details are concealed: 1234 xxxx 1516
I think they should also be concealed the same way when viewing the full item: 1234 xxxx 1516
Then, similar to passwords, it can easily be revealed (or copied while still concealed).
Some websites even conceal the credit card number behind asterisks after you move to the next input box. For example, you enter the card number, tab to the expiry date, and the card's digits are concealed. The reason for that is the same as the reason I'm suggesting this to 1Password:
I feel uncomfortable when any sensitive information is exposed on my computer screen when I am in public (Starbucks, airport, etc.), in the office, etc. because anyone nearby can see it, take a picture, etc.
So, I do not agree that sensitive information should be shown by default on the screen unless I've selected to reveal it. I rather just copy it while concealed or reveal it when I want to see it. Usually, all I need to see is the last 4 to confirm something (some call centers and websites use the last 4 as a soft verification).
Thanks for considering!
