I will be brute forcing the password, depending on the complexity of the password it will take max 1 or 2weeks, if it doesn't break till then i will use other methods.
If the account has 2FA enabled, the difficulty of the breaking in will be increased greatly.
Any info about the target would help out greatly and if you have a lot of info about the target that makes wordlist attack possible.
If you're interested you can pm me on telegram @doingsquats.
