Blockchain.com (formerly blockchain.info) has over 50 million generated wallets since its inception. If you’ve lost your mnemonic words and forgot your password, you can’t count on any support. Passwords and mnemonic words are also not stored anywhere!
If you forgot your password, but you know from which e-mail you created the wallet and you still have access to the mailbox associated with it, you are able to check all wallets that were created in the past in relation to the given e-mail.

If you are unable to remember your password, there are several other options to recover your encrypted wallet.
You can use btcrecover to download an encrypted backup.
You can download Btcrecover from: https://github.com/gurnec/btcrecover
To do this, you will need to install some Python libraries and be a little familiar with the command line. If you have a wallet.aes.json backup file and you don’t remember your wallet ID, you can import your wallet to a new blockchain.com wallet.

What if you created a second password on your wallet that you don’t remember? You are able to brute force a password if you have GPU cards (NVIDIA or AMD graphics card) that are capable of trying thousands of different passwords per second. In addition to having graphics cards, you can use software such as hashcat to do the password cracking for you.
Hashcat can be downloaded from: https://hashcat.net/hashcat/
If you can’t find any password, you can use several different word lists. In the link below you will find a popular word list that can be useful if you have set an insecure password: https://weakpass.com/wordlist
Make sure you have plenty of disk space and bandwidth. Many of these lists can be around 10-30 GB. If all of this is too hard for you, there are professional services like keychainxpro.com that can help you recover your blockchain.com wallet for a fee, or blockchain.info.
