IMAP clients generally need to use application-specific passwords in order to access accounts that use 2-step verification. You'll need to generate a new app-specific password, then use that to set up your incoming/outgoing servers instead of using your regular account password. Google's support page (linked above) includes instructions for doing this. ...
If you signed up for 2-step verification, you may need to enter an application-specific password in place of your regular account password. You can generate an application-specific password when you are authorizing access to your Google Account. This process takes a few minutes, and you only need to do it once per application or device.
Note: For Android ...
This is actually what you have to use backup codes for.
If you can still access your old device and it's rooted you can backup the database and restore it on your new phone.
However, if you can no longer access your old phone and you do not have recovery codes you have to contact their support and sort it out with them.
This is the purpose of two-factor ...
If you have a backup application, you may be able to back up the app's data, sync it to the cloud, and restore it on the other device. The one time I tried that it just made Authenticator crash on startup.
If you saved the secret keys you're given, which is a good idea as long as they're secure and separate from your passwords, you can re-enter them on a ...

I found a partial solution to my question:
I was unable to use the 2-step verification using SMS message. I went to my google account settings and changed to Voice Call instead of SMS
Go to https://myaccount.google.com/ (make sure it's logged in to your desired account)
Select "Sign-in and security"

Did you took a copy of Backup Codes which are provided while enabling 2-Step Verification? They can help you to login if you've them.
Otherwise, try resetting your password. That's the only option left. And, from the next time install the Google Authenticator App from PlayStore as it creates code by itself and comes very handy. No reliance on SMS/Call.
I found the solution. I have disabled some permission on Google play services. This is used to work well. BUT maybe due to google play services upgrade automatically or something else I don't know, it no longer works with some permissions disabled. After enabling all permissions to Google play services, it works again.
Like most other 2FA implementations, Yahoo also supports "App Passwords" for apps and APIs which do not have a proper login system to authorize the 2-factor login.
These are static passwords which work as if there's no 2FA implemented at all. Be sure to never share such password with anybody as it bypasses the 2FA.
Yahoo has detailed steps to generate the ...
I just experienced the same problem and according to WhatsApp support there is no real solution for it.
I also got a new SIM with a phone number that was used by someone else before. This previous users WhatsApp account had two-step verification activated which means I couldn't activate WhatsApp since it was asking for the pin that I don't have and that can ...

To regain access to your phone, first you have to regain access to your account on a computer. Like Dylan said, this can be done using your one-time backup codes. (You saved those codes, right?)
Once you've done that, generate a new application-specific password. (https://accounts.google.com/b/0/IssuedAuthSubTokens or Account settings -> Security -> 2-...
