i have Blockchain.info wallet and want to sign message message .

Used google and Find

i follow it but not found More Option also click all bottoms not found More Options  or sign message only verify message

Any Help ?

You can signed message only using blockchain.info wallet with your imported address, not the watched only address. So if you're using its HD wallet then there's no way to do that. Only importing your private keys to some wallet that has a feature of signing message like electrum for desktop and mycelium for mobile.

I used this https://support.blockchain.com/hc/en-us/articles/210353833-What-is-message-signing-and-how-can-I-do-that- (https://support.blockchain.com/hc/en-us/articles/210353833-What-is-message-signing-and-how-can-I-do-that-)  and was thinking they talk about web wallet thx
Now
what mean by "imported address"??

Is there any web wallet Support Sign message ?

Imported address are the address which is not from your blockchain HD wallet. Its either from different wallet where you can access the private keys (https://en.bitcoin.it/wiki/Private_key) and import it to another wallet. Heres how you can import private keys from wiki https://en.bitcoin.it/wiki/How_to_import_private_keys.

I dont if there is a web wallet that supports signed message. All I know is from desktop and mobile wallet like what I mentioned above, or you can use coinomi also.

You use new wallet? As my experience i can sign with my wallet have some transactions. I dont know this is work or not for you but i think this is problem. You can go to Settings -> Address, and can try. Hope you will Sign you signature.

As what I explained earlier this signed message feature will only works on blockchain.info wallet from imported address, now it seems that OP is using its HD wallet not the imported one So basically he cant do that.

i use web browser only to access to my wallet only click on https://blockchain.info/wallet/#/login (https://blockchain.info/wallet/#/login)

i go to Settings > address and only find box to check verified message not found and bottom to verify message

i will download wallet ant import address like @bL4nkcode say

oh well, that is quite simple but Lengthy process as well.

Download - https://iancoleman.github.io/bip39/

Go to your Blockchain.info wallet and get you Recovery Backup Phrase from there. Now put that 12 words Phrase into BIP39 Mnemonic.

Now, you can check the Bitcoin addresses with their private keys and copy one of them you need. In case you don't find then probably you are not using the default account of the blockchain, go to settings --> Address check how many accounts you have there and change the account's field to 1 or 2 or 3 depending upon the list. Always Start counting from 0 as default account is referred as 0.

After that go to http://brainwalletx.github.io/#sign put your private key there and type your message to sign the bitcoin address. I know it is hosted on github.io still I would not recommend to use it. Better you download a copy from https://github.com/brainwalletX/brainwalletX.github.io and use it offline as it will be much safer for you.

You again hehe. Theres no need to make message sigining in blockchain.info quite complicated. All you need to do is go to bitaddress.org, create a new wallet over there and import the private key to your blockchain.info wallet.

Its much simpler for everybody doing it that way.

Your suggestion can be applied only to those newly made wallet/address. But on the situation of OP, he's asking of signing message for the address made of blockchain.info. So as what I've said it only implies to those imported address on blockchain.

It's like SM23031997 explained. If you need a mobile wallet, then mycellium should also work with seed of blockchain.info for signing message.

100% of what you posted was already mentioned above, so there's no need to post it again and again which being repetive is such a spammy post/s. Doing anything to post for the signature right?
