I have an old Blockchain.info-wallet from 2015. I have the right password (double checked with the old 17 recovety phase aswell. The wallet ID is also correct and it is connected to my email. Still I only get info about wrong password when I try to login (tried from all different browsers, emptt cache and so on).
AFAIK, old Blockchain.info wallets have problem with login using correct ID/PASS. you can use your "wallet recovery mnemonics (17 recovety phase)" with https://login.blockchain.com/wallet/forgot-passwordCommunication with the support team will be slow and a waste of time, especially with the increase in the bitcoin price and the desire of many people to recover their wallets.
Created an account just to say thanks!
Had an old paper wallet, QR codes dont work, there are 9 words in the mnemonic instead of 12, private key not recognized by other wallets etc etc. Did my head in for quite some time. Never got that link from support for the old accounts.. So thanks again, big stress release here!!!!
