The truth of the matter is, you can't get your password back or make withdrawals from that wallet anymore. That's why they always warn to write down your secondary password and even take a step further to verify if you did by asking you to write it down. It's a step to ensure tight security and avoid the case of missing funds and we accusing them of tempering with our wallets. Let's just hope what you've got in that wallet isn't huge because, it is as well lost.
Wrong, read about these guys, they recovered a wallet with second pass from 2015... Even Dave Bitcoin failed
Hi, I know my wallet ID at blockchain.com I have my main password correctly. I have access to my email address. and I have access to my mobile number. and have access to google Google Authenticator set at my wallet. my problem is I have lost my secondary password used for withdrawal. also I have 8 of 12 word Wallet Recovery Phrases. I have been noted my phrases at a small note book and 4 other word have been noted at the next page and my baby has torn it and then lost. Is there anywat I can have access to my wallet again? I have some bitcoin and some etherium inside it. I can say the approximate amount of bitcoin and etherium in my wallet and the date I have bought them. Thanks
Download a backup of the wallet and run hashcat with your best guess, or google: recover blockchain password, u get many hits
