If you plan to collect ideas from people who already have an account on your site/app, www.neeeds.xyz (I'm the author) has a one-click register/sign-in feature.
You can also take a look at Canny, UserVoice, OpenVoyce...
I'm too joining this feedback management party with my feedbear.com 😬
Also, I'm planning a SSO solution (so your customers can be identified without signing up to FeedBear) in the near future.
