Phone locked while flashing ROM, changed gmail password..

[AC Question]

Hi,
Was just trying to update some tool and my Asus ZX551ML device went into bootloop.. So I just tried to flash the ROM again (taking backup of data on PC).
While ROM was flashing via ADB sideload..

While ROM was flashing I also changed my google password as it was unchanged for a very long period.
Once the flashing thing was done, when I tried to login to my Google account, was continously getting message, Please sign in using one of the owner's account for this device.. IT wont even allow me to sign in using another account.

Researched enough that I have to wait for specific number of hours before that FRP - Factory Reset Protection thing is released..
least 24
max 72
kindly confirm what is latest wait time.

Also if there is any other way to sign in ?
Since its my account, I have the SIM card, all recovery emails, all the purchase history, including CC numbers etc. with me.

Or

There is no option and to wait..
1. This is really no security, but a waste totally.. (inspite of having access to all details, I still cannot sign-in or contact google in anyway..)
2. Whats the overall use of security for a thief, if the bypass shall be gone/take away after 3 days.. as read.
3. Since I got this phone, I have only used 1 google account on this device (like majority of people do), how am i supposed to login to other owner account.. on a new bought phone.. OR
should I contact Asus in this case.

Thanks.

Just an update, the FRP has been removed after 24 hours. (It was been reduced to 24 hours now, earlier it was 72 hours)
Able to login with the old account properly now.
Hopefully, this information might help someone in future..
