Once you create an email id on Gmail then it asks for a password to secure your account from threats. You should change the password from time to time to make it more secure. If you are unable to change the password then, go to the Account & Settings option and from there change the password but before it, you have to confirm your email id. If you still unable to do the same, then contact Gmail customer service to resolve it as soon as possible. https://www.onlinedigihub.com/social-med...ustomer-service
