I just recently tried BitwardenRS and I was wondering why Authenticator Key (TOTP) didn’t have a Toggle visibility option like Password Field. I tried checking the Wiki and found there is nothing about this.
When you are adding or editing an item in My Vault the Authenticator Key is visible and could be an issue if for security if say there is a malware that screen captures your display or someone is spying on you visually.
Hope you can include Toggle Visibility like on Password Field.
