How to download private videos with tubedigger?

[suvi]

I got a link for a private youtube video. I can open it on youtube when I login with my account but once I copy the link to TubeDigger it asks me to login again and then it shows an error saying "Couldn’t sign you in
This browser or app may not be secure. Learn more
Try using a different browser. If you’re already using a supported browser, you can refresh your screen and try again to sign in."

I try to login and keeps on showing this.

How can I solve this and download the video?

Thank you.

Under settings you can change the browser. The 'Android' ones are generally more yt-friendly.
