This feature is only available to imported address/es. Now if you imported the address there and you still can't find the option called "sign mesage", make sure that it is not a "watch-address" because you still need its corresponding private key in order for you to use that feature.

You will only be able to sign messages with imported addresses and with addresses created in old Blockchain.info wallet. If you created a new wallet/account in Blockchain.info, you *won't* be able to sign messages with the addresses created.

Okay thanks for clarifying.Yes I'm using an address made in the old blockchain.info wallet before they updated.Never knew newly created addresses don't have signing provision.

Blockchain.info now uses hierarchical deterministic(HD) wallets. Many HD wallets don't allow you to sign messages. You will have to use tools like https://github.com/iancoleman/bip39 to first find private key of the address you want to sign message with and then import address to a wallet or use a tool.

Any updates to this as there is no way I can sign a message in blockchain, the only options I get is edit name or show xpub?

Did you read the main post seriously ? Wasn't that enough ?
According to their official post : https://support.[Suspicious link removed]/hc/en-us/articles/210353833-What-is-message-signing-and-how-can-I-do-that- it's possible for only imported addresses.However,I'm still able to sign messages from the original address on blockchain.info.Follow the same steps mentioned in the link above.

Thanks for the prompt reply, so I will need to import an address from a separate wallet then?

No,you don't have to,the last I checked.Like I said,I was able to sign a message without importing an address.
Here's how you do it :
1-Go to Settings
2-Click Addresses
3-On the right hand side of the address you wish to sign a message from has "More Options ->Click ->Sign Message"
4-I checked it just now and it's working.

Are you using blockchain.info? As I do not get those options after I click on manage, all I get is change the address or delete the address

You will only be able to sign messages with imported addresses and with addresses created in old Blockchain.info wallet. If you created a new wallet/account in Blockchain.info, you *won't* be able to sign messages with the addresses created.

Thank you!
Yes, I saw.
There is a line of "signature" - what to write? Where to get the signature for the message?
Thanks for the support!

In the last versions blockchain wallet changed his policy and removed some useful features imo. One of these is the ability to sign a message. So, you can sign a message only if you import an address. Till now using this wallet there is no other way. You can verify a message something not very useful since there are many sites to do this.

If you're signing a message, leave it empty. If you're verifying a message enter the signature there, it looks like a long string of random characters (example: IFtLgDZCpvfw0DT70RCLcYXj3Dbjf68sc6pj/C+u5K6IC8PIhHE4Y/ldllt1/yhrZpVW/shFRf7rxQYdsW/CcBM=).

Well yeah, I've just checked out the new blockchain.info (made a new account). Spent a good deal of time figuring things out.

The guide doesn't work. (at least for me)It's probably for old versions or for imported addresses.

The only way one can verify/sign is by importing addresses. (Haven't really tried importing one to confirm,but it's what I've concluded going around their faq/help/etc.)
The new addresses generated by this latest version of blockchain.info cannot be verified/signed. It's still unsupported. No idea why. Or if this will change.

I do have the same problem as you and i believe the new adress hasnt yet the option to sign messages it has been reported sometime ago about those, we can edit name and show xpub and just from new adress, the funny thing is they charge for we transfer bitcoins over accounts, and now there is a message:
Imported Addresses Not backed up by your Recovery Phrase. Transfer into a wallet to secure funds.
Transfer All

Meaning they wanna get more funds while we do use our old adress, i do hope they allow us to sign messages from new adress and stop being greedy to the point to charge us to transfer funds between adress since has no costs for them.

I have same wallet version. So I imported one of my used address (that is from same wallet id) only to see if I could sign it. But there is not this option. Click to more options right from imported address and only options are: archive, transfer, spend. Moreover, they claim in their support that I can sign an imported address /hc/en-us/articles/210353833-What-is-message-signing-and-how-can-I-do-that-]https://support.[Suspicious link removed]/hc/en-us/articles/210353833-What-is-message-signing-and-how-can-I-do-that- this is not working. Looking forward to see what happens in newer versions.

Look the imported adress if belongs to the last version of blockchain.info you will be able to sign a message, just the new adress of the new wallet arent able to sign a message at the moment. Im able to sign any message from old adress, just follow the steps if its an old adress if its a new adress you wont be able to sign messages.

How can I look something like that? That is, which address belongs to which version of blockchain wallet? Where somebody can see the version of his web wallet?. Furthermore I believe that there is no sense to import an address from a wallet id to another address of this wallet. I believe that this (hopefully) working if I import an address from another wallet. I did this only as experiment and I think that blockchain wallet had to warn me that I transfer funds between addresses in the same wallet. Instead of this, asks money for the miners giving option to transfer or spend that money or to archive the address. This make sense knowing that if I want to transfer money between addresses need to pay fees to miners. Truth is, that I take money from one pocket of my pants to put it another. May be in this case is better (calculating miner fees) to transfer all of my funds to a new wallet only in one address.

I dont believe its possible to trace or know if the adress is new or old if has no transactions at it, can be very old but without an adress i doubt you can know about those. Its ridiculous blockchain new feature of charge to we transfer funds between our adress, i have more then one adress and i dont moove my coins into a single adress because i have to pay for something should be free.
