I forgot my ROBLOX password on my main account

Ok so, most of you might know my main ROBLOX account is dogpizza11, well bad news.

I FORGOT MY FUCKING PASSWORD

Yeah but do not worry bout me I got a backup account called AngryBird301167 (i named it that because I liked Angry Birds back then). So hopefully I can remember my password, and get my main account started again! (also i have no robux on AngryBird301167 because I spend it all on Welcome to Bloxburg and Jailbreak Gamepasses xD)
