How long does it take to verify the verification code of Google account several times?

This situation needs to wait for 24 hours to return to normal.

Google account mobile phone verification code needs to wait for 24 hours to return to normal after multiple verifications. If the Google account appears abnormal login for many times, the system will prompt you to enter "number B" for verification. At this point, the original error message "This phone number has been used for verification many times" has disappeared, which means that the system automatically lifted the restriction of multiple verification of Google account mobile phone verification code.
