How to sign in to YouTube, a.k.a by pass the "Google couldn't confirm this attempt to sign in is safe. If you think this is a mistake, you can close and try again to sign in" warning.

uYouPlusExtra

uYouPlus but adds the YTDisableHighContrastUI & Additional YTUI Colors that should’ve been added to the original uYouPlus by qnblackcat.
YTDisableHighContrastUI: This tweak helps remove the new contrasty looking UI that was first introducted way back in 2020 August/September.

Main IPA: 17.36.4

F1: Updated YouTube to 17.36.4 + Submodules Updated
F2: Rebranded Name from YTDisableHighContrastIcons to YTDisableHighContrastUI
F3: Google Sign In Setting Disabled

Note: qnblackcat formatted and decided to remove the old code for 16.42.3 and I had to remove support on making 16.42.3/16.46.5 or older because some of the options will not work as intended since some of that code is gone. so I suggest downloading the last-supported version of the ipa below if you do need it!
