Every time I restart my Mac login screen popped up and I give my password(old password). After that successfully login, login screen pops again and this time I write my password(that I changed to new) again to log in properly. I looked up this issue but couldn't find a solution.
It happens on Sierra and High Sierra
I think what is happening is that the first password screen is from the preboot environment (before the encryption of the HDD is released), then the main OS boots (you see the progress bar) and finally you log in to the main OS.
Somehow your password as known to the preboot environment did not get changed when you updated your password in the main OS. As such the preboot OS is not able to log you into the main OS once it is booted as it does not know the new password.
I'm not certain of the solution, but I'd start troubleshooting by resetting my OS 'new' password to the old one.
Check that you can log in with just one password
Then change your password back to the new password (or another one). Hopefully that will write both 'preboot' and 'main os' copies of the password.

Hello egrimo,
Are you using FileVault? Is this a real login display or is it asking for your keychain password?
If you are using FileVault and this is a true login dialog, then go to System Preferences > Security & Privacy > FileVault and see if there is a button at the bottom to enable users to login to the device. Click it and follow the instructions.
If this is a keychain issue, you just might need to change the password on your keychain. In some environments, especially workplaces using Windows networks, changing your password might not reset your keychain password as it should. If that is the case, then you will need to manually change the keychain password.
This solved my issue I didin't know that there was two boot password, changing old and new solved it.
Must Login Twice ?
