Signing a message requires access to your private keys, you don't want to do that using an online website. As for verifying, then you can use this tool:

https://bitcoinmessage.tools/verify

I'm not sure which wallet you're using but Bluewallet allows you to both sign and verify messages.

[Crypto Library]

You can also use the mobile apps that are giving these services.
Anyway here is some list , I think it can worked for you. Moreover, if you want, you can visit this topic of shorena. For beginners, the tools,
I will prefer you to visit blockcain.info and Mycelium(apps) for using on mobile. And for verifying you can use any of them preferring brainwallet.org

Not securely.
There is code out there that allows you to do it. IF you can run it on a server that you control and can set it that only you have access to it then yes.
Beyond that no.

There are some phone wallets that allow you to import a private key so you could do that.

BUT ONCE YOU HAVE THE PRIVATE KEY ANYPLACE OTHER THEN A HARDWARE WALLET / AIR GAP PC IT'S NOT SECURE ANYMORE AND ANY FUNDS IN THAT ADDRESS ARE AT RISK.

Thank you for your kind information but it's not working for my private phrases. It asked for only private keys, Actually I used trust wallet.

Thanks for the information mate, I will try and check the thread.

Which wallet asked you for private keys? I'm not sure I understand. You should be able to import your seed phrase from Trustwallet to Bluewallet and then sign a message just fine.

I'm also answering while assuming that you're talking about bitcoin messages, and not ethereum's (or something else).

[BitMaxz]

I think the private phrases he talking about are the seed phrase backup.

@OP if you have that backup you can import it to any mobile wallet that supports signing messages like they said exposing these backups(private keys or seed phrases) online is very risky.

However, you can import these seed phrase like to mycelium wallet offline without the internet and make a signed message there and verify it to the link shared by OmegaStarScream.

It should be work unless you talking about other coins like this one on trust wallet community "Issue with signing a message from imported wallet"

sign messages from my mobile because sometimes when Im out of my home I can't use my pc software for that.

I'm curious: why would you need this? I've made Bitcoin payments when I'm not home, but I've never been asked to sign a message. I can't think of a single reason why I would have to do that when I'm on the road.

Exactly I do see that message signs is in unique cases not every minute. However, I can't think of a reason as well

And when the unique cases happened when you are not in home then what you will do ? That is why I'm asking buddy. Everyone has different reasons, right buddy?

In that case, for such unique situations, go for a wallet app that has the features you need, like the Bluewallet mentioned earlier. As you have already been informed, signing messages requires your private key. Using an online service for that purpose would pose a significant security risk.

First, like others said, signing a message requires a private key of the public address and if you use an online website to do that, you leak your private key. When you leak it, it will no longer be your private key. You can lose your bitcoin by that website owner, very likely to lose it because who will ask you to leak a private key, maybe only scammer.

Next, about signing a message to prove something, mostly it is to prove that you are a real person, not an impersonator, hacker, when you are dealing, trading with another person. Mostly it does not happen and you won't be in that situation.

Now, if you need to sign a message on mobile, you must - in my opinion, have two wallets, two public addresses and stake them somewhere, one on computer and one on your mobile. When you are hanging out, on mobile, you can sign it on mobile with that mobile wallet. I don't recommend to import your wallet on computer to your mobile, just to sign a message. It's risky.

[sherrylove]

As far as I know，any site or tool need to generate address online is not safe.

You can use it without internet ,if you want to sign or verify your trans.

at least ,you can turn off the internet and then (sign or verify), and then turn on the internet.

These steps is boring but save your privekey on your ownside .

good luck man .

You need a software wallet at the very least. Like mentioned above by OmegaStarScream; Bluewallet should do fine. Although I am not sure if the phone app or the desktop version is being referred to.

If you want to sign a message then do not use your internet browser! Any website asking for your private keys is a scam website. I have never heard of using a webwallet to sign a message. In fact, I would advise you to not trust anyone who tells you to input your private keys into any website.

Keep your keys safe and be more vigilant when dealing with your money. There are a lot of scammers and hackers out there, hoping to lure the unexperienced coiners into a trap... Honestly, your opening post basically screams "I'm a target"...

Message signing can easily be conducted without an internet connection because the process itself is nothing else but fancy manipulations with strings and long numbers, which require almost zero processing power. One of the ways you can solve your problem is by installing a reputable mobile wallet, feeding it with your secret phrase, and using its internal functionality for creating and verifying Bitcoin signatures. But if you want to feel like a hacker, then I suggest a different approach: install a Termux[1] console on your smartphone and use it to run small message signing/verifying scripts such as bmt.[2]

I was referring to the Android/iOS wallets since OP wants something to sign his messages while he's away from his PC, there's also a desktop version[1] but it's only available for MacOS users.

you can use this online page https://bitcoinmessage.tools
It will support your trust wallet or exact private key from it but it is better for you not to use it with a private key that contains bitcoins, or at least make sure that the wallet does not contain any cryptocurrencies before listing your private key on that site.

But isn't it easier to create an account in a new wallet that supports bitcoin sign/verify message or use other methods such as PGP?

And when the unique cases happened when you are not in home then what you will do ? That is why I'm asking buddy.

Whatever your reason is, please do not use your funded wallet's private key(s) on this:

This is the most popular (not Trusted) signed message verification website used in "Stake Bitcoin Address" thread, but it can sign as well.
It's open-source but only supports legacy p2pkh addresses.
Here's the source code so that you can use it offline and to audit as well: https://github.com/brainwalletX/brainwalletX.github.io
Online webpage Link: https://brainwalletx.github.io/#sign

You can't use QR code though, I believe message signing feature through QR should also be implemented in the wallet that'll sign to work.
It more inconvenient and doesn't have any security advantage than a simple message signing feature, so I don't think wallet developers will add such feature.
