No.
Blockchain.com wallet has a very clear security policy.
They recommend that you follow all security steps to secure your account. One of these steps is to generate your mnemonic phrase, which you didn't.

Your backup phrase is the most important of all security measures. It is the key to ensuring your access to your funds if you forget your password or Blockchain is unavailable
Now, there is very little you can do, as you didn't follow the basic security procedures.
You will need to log in in your account using your created password.
are you using your wallet ID to log in?
Your wallet ID was emailed to you when you created your account. It is your wallet "username". You need it and your password to log in.
If you are able to log in, you need to back up your mnemonic phrase ASAP.
