Super helpful, thank you.

Any idea about the minimum password length by chance?

I found this:

Quote
As of January of 2018, Blockchain.info enforces the following requirements on new accounts:

- Passwords must be at least 10 characters long
- Certain strings (“1234567890”, “abcdefghij”, the same letter repeated 10 times) are not allowed

This appears to be largely the same set of criteria that the company required in January of 2012, when they wrote: “We require a password of at least 10 characters in length to ensure that even if our database is compromised your wallet will remain secure.”

At the risk of stating the obvious, this means that whatever password you chose for your Blockchain wallet is at least 10 characters long.

Update: However, in February of 2021 we discovered a 2017 Blockchain password that was only 9 characters long. So, if your Blockchain password was created earlier than January of 2018, a shorter password length is possible.

Try to email Dave from WalletRecoveryServices. He've been dealing with all types of wallets since many years now, so he might be able to give you a more accurate answer.
