You can self-host Feedbin or you can get a paid account for $30 USD.

Lots of great functionality built-in. I use Unread app for iOS as the front-end instead of Feedbin’s web app. A paid Unread account would also give you RSS feed hosting, but less feature rich.

To try and thwart malicious scripted login attempts, some sites expect a manual keyboard action on the username and/or password fields.

You can use your password manager to populate the fields but then click each and add then remove a character. That usually handles it.
