This question already has an answer here:
Everyone knows Google linked everything in one account. YouTube, Gmail, etc.
I'm trying to recover my YouTube account but it send me to my Google account so I don't remember that password. I go to the options that help me get it but the options there are truly useless as I do not remember when was the last time I used it because I only use YouTube (never my Google account) neither when I created it because I had that YouTube account for a long time and suddenly there were some emails about some merging between this two accounts.
Can't Google just send me a recovery password/code to the my email? I will be the only one supposed to see it.
