Wow shorena, you are the bomb! Tip sent!
Thanks for this useful guide, i was searching about this before i stepped into this thread.
Can somebody please explain to me how to sign message with Xapo wallet?
You can't. I highly recommend you to use a desktop(or mobile) wallet. If you want use an online wallet, use Blockchain.info. Other online wallets are insecure.
But I need the address on my Xapo wallet to sign a message
btw, why is other online wallets beside Blockchain.info are insecure?
Also, the reason online wallets are considered insecure is that you have to share private key with third party (think of you sharing your home key). Only blockchain.info stores private key in your device (they encrypt your private key on your computer and then upload to server, so you still have to trust bc.info to encrypt your key), that's why MZ suggested you use bc.info (or desktop wallet).
But if we stores private key in our device, it means if we lost our private so we lost everything.
That's why Xapo don't want to share the private key, so if the private key lost Xapo will refund our balance. (CMIIW)
Do you tell another person to create a bank account for you and tell him/her to withdraw money when you want? Or do you create a bank account yourself and never share with another person?
Yeah, that's make sense too. Okay so it's more safe to use Blockchain.info than Xapo, then I will move to Blockchain.inco
btw, I used to use Blockchain. But because there is so many faucets offerig more rewards for Xapo users, so I moved to Xapo

I'm not asking about offline wallet, I'm asking about the best online wallet service. Offline wallet is not compatible with my device
What device are you using? Why not use PC. Sure its the most secure way, mobile phones are all surveyed.

Thanks for the answers, so keybase.io can not be used to sign a message and thus should stay out of this guide, agreed.
I just did the first few dos and don'ts. Feel free to suggest more.
I also found this very neat feature on the brainwallet page. It allows to create a link with the address, message and signature included. Creates a very long link obviously as it includes everything in plain text.

I think "Don't sign a message in a compromised device" should be in dos and don'ts.
done.
Brainwallet's this update looks cool. They have automated this instead of a button. So, maybe, new pic is needed.
Added it on top of the todo list for now, I probably have a little time for it tonight or tomorrow.

I think that the easiest way is to use keybase.io , you won't have to have any knowledge about any program,it is really simple.
The bad side is that there is a long queue to get an invite,you just have to sign up and wait
Keybase.io's btc address system does not verify the address' ownership, so it is not perfect. Also you have to store private key to do things easily (and they recommend that!) which doesn't seem so good.The bad side is that there is a long queue to get an invite,you just have to sign up and wait
From what I read about keybase.io they use PGP to link several accounts to a single PGP key. They also offer to verify bitcoin addresses, via said PGP key. Can anyone with an keybase.io account verify the above? I can also check around and see if I can get an invite to dig into this.
- You put the bitcoin address.
- Wait for keybase.io to save the address, (~10 secs).
- ...
- PROFIT!
They offer coinbase.com OAuth, but that's different issue here.
True. The two things I didn't agree with them are
- They recommend storing encrypted PGP private key in their server.
- They doesn't verify whether Bitcoin address is owned by the same owner of PGP key, obviously by asking a Bitcoin signed message from submitted address.
I have already proposed this but I didn't get any response from them. https://github.com/keybase/keybase-issues/issues/1400
