Browser Extension for

As opposed to annoying password manager extensions, the PassHub extension is a non-intrusive tool to fill username/password fields in login forms and bank card data on payment pages.

By no means is the PassHub extension a silver bullet, but rather a semi-manual assistant that shows a choice of the appropriate accounts and fills usernames and passwords into login forms on websites. Automatic form filling is more about guessing, not about well-defined algorithms. Generally, the PassHub extension works on approximately 80% of sites. For other cases, use the basic Copy/Paste technique of itself.

NOTE. For Chrome browser only: pin the PassHub extension icon to the Chrome Toolbar. Click the puzzle piece-shaped Extensions icon next to the account icon and then click the pushpin next to the PassHub extension.

The extension consults the PassHub browser tab if appropriate accounts are stored for the current page URL. There may be more than one suitable account. All will be shown in the extension pop-up.

NOTE: Sometimes, the username/password form appears with some delay, so the last method only opens the login page but does not fill the form. Just continue by opening the extension popup as described above.

3. Payment Card Autofill

When the extension icon is clicked on a page with a payment card form, the extension detects specific field names and shows a list of stored cards. Just select the desired card to auto fill its data.
