Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
If that is an Android phone, then if you have entered too many wrong passwords,
A. you will need to wait about 72 hours, leaving the phone quite alone until then, to get another chance at entering another try at your password, and
B. you may, if your password ***** ***** gone, need to either retrieve your password ***** if it has been entered on another device... or, likely, need to go to a computer, try to log in to the account, get refused for a wrong password, then use the 'Forgot password?' link to retrieve it or reset it - if that option is either possible or practical, for whatever number of real-life reasons.
Good. I hope it goes well. If not, there's another alternative: to hard reset your phone back to factory conditions. But: if you do so, you have to authorize the operation by entering... your password! of course. So it's best to try what I said previously (A and B paragraphs in my answer) before thinking of doing so.
