I have a Samsung Galaxy running the latest version on android, the mobile had a lot of annoying popups, so I took a full back up of my phone on Google Drive where I got 2 TB of storage. and I specifically went to WhatsApp and I did a full backup which went successfully. So I thought I am fine now and I have all the backup on google drive and google photos.
I did a factory reset for my Phone, and on startup I chose to restore from Cloud and I login to my google account. now all my apps were restored, including WhatsApp. But when I open my WhatsApp and I confirm my mobile number, WhatsApp shows that it is looking for Backups and it found the backup I did earlier today. But when I chose to restore from this backup, i am prompted to enter a password. First, I thought this need to be my google account password, but the login failed, I also tried the old phone pin code, and it did not work either. so what is this password? As i remember I were not asked to enter a password when using WhatsApp and when I backup it? so can anyone help? how i can restore my WhatsApp backup on google drive? without this password? or what is this password?
Thanks
