OK I’ll try.
Saw you can’t log out of Yoroi in the browser desktopversion ,and there were many requests in the pastto make this possible.
Closing the tab doesn’t solve that.
No other solutions available?
Not for Yoroi.
Gero wallet locks automatically (which I personally find very annoying, especially combined with the requirement of having numbers in your password).
Eternl, Typhon, and Flint all allow you to optionally lock your wallet(s).
All of them (including Yoroi) require the spending password (or confirmation by hardware wallet) to do transactions.
So, it’s really only about viewing the wallets (where the information is public on the blockchain, anyway, albeit maybe not linked with the information that it is your wallet).
We are trying to get rid of them, but we can’t see, when they just write direct messages.
Please flag with the flag in the icons in the lower right of the message:
I see it’s still impossible to log out on a desktop,although people ask for it a long time?
Only way is to disable Yoroi extension and then later restore with seedphrase every time?
Secondly I tried to test withdraw some ADA from the wallet ,worked.
When I wanted to withdraw
1,5 ada fee 0,175 ada
2 ada, rejected.? “not enough”
3 ada fee 0,175 ada
3.3 ada fee 1 ada??
4 ada fee 0,175 ada
Differences are minuscule,but why 1 rejection and different fee?
Yoroi is just slowly doing some development again, was pretty much stalled for a long time. Maybe you will have more success requesting that in their support channels: https://yoroi-wallet.com/#/support
For me, logging out/locking is a totally superfluous feature, but if you think it is important, you might use one of the more actively developed wallet apps: https://developers.cardano.org/showcase/?tags=wallet I’d recommend Eternl, but Typhon and Flint are also good.
Hard to tell without looking at your specific wallet. Transaction fee does not depend so much on how much you send, but on the size of the transaction in bytes. And that depends on what unspent transaction outputs in your wallet the wallet app chooses to spend and how much then goes back as change to your wallet.
Higher transaction fees might be, because NFTs/other tokens are moved. Or because after sending out to the recipient, there is not enough left to create a change output in your wallet and Yoroi therefore chooses to just make everything transaction fee.
Correct me if I’m wrong ,so it’s not necessary to shield your amount of cryptocredits you have from strangers/hackers that “visit” your browser?
Keeping your bankaccount open in your browser for every one’s eyes should be seen as acceptable then to ?
It all depends on the attack models.
First, a wallet app is very, very different from online banking. You are not logged into some account remotely, so there is nothing to log out from. Everything happens on your device. What can be done is locking the account.
(That’s also why wallet app providers cannot help much if a device is lost or broken and you don’t have the seed phrase. There is no account on their side, there are just the transactions on the blockchain.)
With all wallet apps I know, you need the spending password for every single transaction. The private key(s) do not seem to be cached in unencrypted form anywhere.
But they are obviously saved encrypted with the spending password somewhere, since you don’t need to give the seed phrase every time. So, if someone gets access to that encrypted (master) key, they don’t need to crack the very long seed phrase anymore, your more or less secure spending password is enough.
If the wallet app locks by encrypting everything – including public and private keys – a second time that is an additional security layer (if it is another password). But if they do not, it is just a user interface thing helping against people who get physical access to your device. And helping only a tiny bit, since if they have physical access, they can just copy the storage of the browser and find everything in there.
So, locking wallets (“logging out”) is mostly a privacy measure against people having physical access to the computer, not a security measure. If there are no people getting physical access (because the computer is in my flat and there are no other people here), I don’t need it. If there were, I would probably lock the whole computer, not just the crypto wallets.
If the fear is that the computer is compromised remotely, locking won’t help much. Adversary or malware could just wait until you unlock and grab the password then. Almost the only thing helping against compromised devices is either an air-gapped machine or a hardware wallet.
