Theres apparently a second way into Snow Veil Sanctum (mentioned in the trivia) but the pull chain to open it is on the inside so on a console you'd have to try the plate glitch to pass though or on a PC use the command TCL (all caps and type it again to turn it off) on a PC you could also just teleport inside with the command -

coc SnowVeilSanctum01

Or one of the other location id's on the wiki page, the second entrance can apparently be found by walking from Snow Veil in the direction of Winterhold.
