Which are some good instant exchange that does not require login?

[UserU]

There's one alternative I could think of, casino sites. You could deposit, exchange and then withdraw.

Might not be appropriate but at least there's no KYC nor registration.

How about the classic myetherwallet one? https://vintage.myetherwallet.com/#swap. It's easy imo and you don't require to login, just directly send your coins to the address.

They use bity.com in the back end.

You still want to convert your 1 BTC to ethereum without login to any sites?

Then visit Currency exchange section on our forum where you can get deals from trusted members.

Currency exchange section is primarily meant for crypto to fiat exchange and vice-versa.

Why you dont want to login?

You can exchange that quickly with blockchain.com's exchange though it requires you to login.

Can you answer why? P2P would only be your choice if you insist.

Blockchain.com requires ID verification for Crypto Swap. Ref: https://support.blockchain.com/hc/en-us/articles/360018352731-How-to-exchange-cryptocurrencies-using-Swap

Yes it requires to login but it's quick to trade there. Can you answer why you want no login required exchange?

Logging in won't take 1-2 minutes and you can place order there so quick.

Let me requote what has been posted previously as an answer to your question.

Why you dont want to login?

probably to avoid KYC, personal data collection, and to be fully anonymous
having a login means registering an account which usually followed by KYC procedure
but if the reason is avoiding KYC, most exchanges without fiat trade usually do not require KYC
@OP so telling us the reason can help us point you to exchanges that fit your needs, or some good advices

Where did you read this? According to the rules on currency exchange[1]

Altcoin (LTC, NMC, FTC, etc.) trades belong in Marketplace (Altcoins). However, if the trade involves bitcoin (ie. Buying Bitcoins and cows), it can stay.

Don't forget to use escrow.

Stumbled upon https://coinswitch.co and it looks pretty cool and easy to use.
Thought it could help you in the near future.
Also for 1 BTC, you get to exchange to ETH with your favourite exchanges such as Binance, Huobi, HitBTC without even logging in

1. Enter the amount of BTC you would love to exchange and click on view offers

2. Different offers from different exchanges will be listed, usually, those that don't require a login. Select your preferred offer. The recommended offer usually has the best rates.

3. Click on the exchange with binance, huobi etc button. You will be asked to enter your ether address where the exchange ether will be deposited. Enter it, Tick the "Agree terms and privacy policy" checkbox and then click the next button below the page.

4. A page showing the BTC deposit address will be shown next. Once you have deposited, the Exchange process will be initiated automatically. The order will take 10 -20 minutes depending on the bitcoin network speed and it will be complete once the BTC is deposited in the address.

- Since it's a new service to you, i recommend you first try out with small amounts
- Please, you should also do some due diligence before trying out. read their terms, read feedback from different users.
- I am not trying to promote the website in any way. I am just trying to help based on what you asked for.

Appears to be a fantastic option indeed.

I haven't used them so not sure if you need to log in at all but it didn't appear so from the tutorial video.

I did see this not to long ago, here's a link to the thread here on the forum.
FreeBitcoins.com/swap

This was posted on the currency exchange board, I think you would have found what you were looking for posting there or service discussion. Good luck.

I would bet on this, problem is its extremely rare to have reputable service like that.
Someone mentioned changer dot com as reputable, not sure here, maybe it is from all different you have to choose from but you don't have much choice in this department.
If Bitcoin want to be anonymous there should be more services like that to be honest.
