That definitely looks like an issue on the site itself David. Not sure how LastPass is unaffected - at a guess, does LastPass leave the second box completely blank rather than filled with dots?
Here’s the code from the login form at the top of the page:
<input type="text" class="textbox default-value" name="vb_login_username" id="navbar_username" size="10" accesskey="u" tabindex="101" value="User Name" style="color: rgb(119, 119, 119);">
<input type="password" class="textbox" tabindex="102" name="vb_login_password" id="navbar_password" size="10" style="display: none;">
<input type="text" class="textbox default-value" tabindex="102" name="vb_login_password_hint" id="navbar_password_hint" size="10" value="Password" style="display: inline;">
As you can see, there are actually three fields, though the middle one is hidden from view ( style=“display: none;”). That field is the actual password field. The one you can see is the password hint field and it is a plain text type, so it won’t replace the contents with dots or asterisks. I’d guess that Bitwarden is putting your password into both the hidden one, which will log you in, and into the hint box that’s in full view. To test that, let Bitwarden fill in your details then make a change to the visible password. I think it’ll still log you in as your actual password is correct in the hidden field.
Maybe let the site moderators know there’s an issue. In the meantime, if you don’t want Bitwarden putting your password into that plain text field, add a custom field called vb_login_password_hint with no value.
