Vivaldi Browser Password Secrets Vivaldi browser stores all your website login passwords in the “Login Data” file at following location [Windows Vista/7/8/10] C:\Users\[user_name]\AppData\Local\Vivaldi\User Data\Default\ [Windows XP/2003] C:\Documents and Settings\[user_name]\Local Settings\Application Data\Vivaldi\User Data\Default\ This “Login Data” file is stored in SQLite database format. It contains database table called “logins” where each website login details are stored.
