Hi There. I am Bing and I look forward to helping you with your issue today.
Which email service are you referring to? Gmail, Yahoo, MSN or AOL?
Okay, once clicking the link of Forgot My Password, did you go through Gmail's question about your last known password ***** other security questions? Did it ask you for the secondary email address?
Did you set up a secondary email address just for email recovery? If you can't remember, try clicking "Try a different question" and see if any question is related to your secondary email address. This is the most efficient way to recover your Gmail account if 2nd email address is available. See the attached screenshot.
If you can't answer any question, we can't help much. We are not magician, even Google team could not help you if you could not provide the answer as evidence.
I am thinking if you are not familiar with the way to answer Google's questions. If yes, I would like to offer remote assistance to you so we can share the same screen and I can even operate the computer to help you step by step. Otherwise, it would be a lengthy chatting process with no efficient result.
That question is NOT for your email address, it is just an example.
All the Gmail questions to you were actually set by yourself when you signed up the email service with them. Therefore only you know the answer. No one could know that. That's basically why you should trust Google's service. If any one like me could recover your email box without having your answers, will you trust your emails box and Google's service? If you don't trust it, what's the point for you to recover it?
Again, it is highly recommended to start a remote assistance in order to let me know what is happening at your side and how to handle the process. Be aware, if you handle this in a improper way, Google may detect it as suspicious email attack and will lock the account at all, then you have no chance to DIY yourself.
If you really have no ANY idea about ANY of following questions:
What was the last password ***** you remember (must have)?
When was the last time (month, date, and year) you were able to sign in to your Gmail account (must have)?
When did you (month and year) create your Gmail account (must have)?
What was the answer to your security question?
E-mail addresses of up to 5 frequently emailed contacts.
Name of up to 4 labels.
What was the first account recovery e-mail address that you remember?
Name up to 4 other Google products that you were using with your Gmail account and also the approximate date (month and year) you started using them.
Phone numbers that you may have associated with your Google account.
Information about how you lost access to your Google/Gmail account.
Then go to Google's email support page, follow the instruction and try your best to answer the questions. If you could be asked for submitting a summary for their investigation, that could be the last chance for you. Good luck!
BTW, in most situations, you should be able to answer the highlighted questions below, if you were the owner and you did use it before.
When was the last time you were able to sign in to your Gmail account?
When did you create your Gmail account?
Any feedback please?
