Same problem here. I tried many different passwords.

This normally means that you don't have old crypto wallet setup so there is nothing to import from
Please create a new native wallet by clicking on the bottom of that page

We will improve the experience once this issue is closed

Thanks for your reply!

The thing is that I do have a Brave wallet (and the password seed).

What is to be done in this situation?

[darkdh]

@Tynael you can restore wallet from your previous seed on new Brave wallet.

But could you provide some data that can help us to narrow down the issue? We will only access to your encrypted data, we cannot decrypt it without your password.

If you can help, follow these steps:

1. Go to brave://flags/#native-brave-wallet and disable it and relaunch
2. Go to brave://extensions/?id=odbfpeeihdkbihmopkbjmoonfanlbfcl and enable developer mode
3. Click Inspect views -> background page which will open a console
4. Paste chrome.storage.local.get(['data'], (result) => console.log(result))
5. Right click on 'KeyringController' from result and select Copy object
6. Send the result to anthony@brave.com

Thank you

I got this when using passwords generated by keepass:

So basically, Brave requires special character in password, but refused any generated password with special characters:

A more secure password is required for Brave Wallet

Same issue here in march 2022.

[mishmanners]

March 23rd, 2022, still the same issue. Ironically, I'm at an NFT, blockchain, and web3 conference. People talking about this and it's still not working. Please try and fix this ASAP. It doesn't give us a lot of confidence to use Brave wallet when it doesn't work...

[fcondolo]

Same here. Brave does not seem to like my MetaMask password.

[alvaro761991]

Same here. using Brave Beta

[sajanjswl]

Same for me!

Brave won't let me import my MetaMask wallet with my MM password.

1. Be your own bank
2. Use the same password on multiple accounts
3. Share this information publicly

Really?

I think you might be missing the point, this is a design point of Brave. It means that you can bring your own wallet.

The issue is that it won't integrate with MM at all and raises a 'JSON data not expected' error.

This issue appears to occur when you have a "$" character in your password, which is the case for me. When I intentionally type a wrong password that does not contain this character, I get an "incorrect password" error instead.

I am going to have to install another browser to use with MetaMask until this is resolved, which is unfortunate.

[antonok-edm]

Also observed this with someone else's installation. They had MetaMask installed previously, clicked the button to import from MetaMask, pasted in a long random-generated password (including special characters) from their password manager - and instantly received the JSON data is not expected validation error under the password input. They are on Brave v1.37.111.

I don't have "$" character in my password and I keep getting the message.

[kjozwiak]

The above will require 1.38.106 or higher for 1.38.x verification.
