Binance announced on Monday (July 22) expanded support for two-factor authentication (2FA) via Yubico's "Yubikey" hardware-based security keys.

A YubiKey security key can be purchased from Yubico for as little as $20 (in the case of their "Security Key by Yubico" product):

A few days after Binance announced that it had suffered a security breach on May, Binance CEO Changpeng Zhao (aka "CZ") said via a "Security Incident Update" published on Binance's blog that the Binance team was "making significant changes to the API, 2FA, and withdrawal validation areas", and as a result, it would be improving Binance's two-factor authentication (2FA) by implementing  support for hardware-based security keys such as Yubico's YubiKey devices, and that in fact, Binance would be giving away "1,000 YubiKeys as soon as that feature is implemented."

Then, on June 27, CZ sent out a tweet that told Binance users that YubiKey support had been implemented and it was in the beta testing stage. He also explained that Binance was at that time only using a YubiKey device (for those customers that had set one up for their accounts) for verifying withdrawals:

On the same day, a Binance support article explained how users could use a YubiKey device for 2FA.

The next day, a Binance blog post announced that Binance had added support for two-factor authentication (2FA) through hardware security keys," and that this was " in addition to the SMS and Google Authenticator options supported on the website and apps."

Furthermore, this post explained that the "Binance website, both on desktop/laptop and mobile, now supports the FIDO2 open authentication standard," which means that "2FA devices that support this standard, like YubiKey, Trezor, and others, can be used as security keys" for Binance accounts. It also said that Binance's mobile apps would be adding this feature in the future.

Earlier today, Binance sent out a tweet to notify users that they can now use 2FA via security keys for "Withdraw & API", "Log In", and "Password Reset"); Binance also, once again, recommended using a YubiKey device as a security key:

Crypto Exchange Gemini Now Supports Stop-Limit Orders

Siamak Masnavi

On Thursday (November 14), digital asset exchange Gemini launched a feature that its users had long been asking for: stop-limit orders.

Product Manager Andrew Page explained via a Medium blog post published earlier today that Gemini is finally offering stop-limit orders, which he said are "typically used by traders to help manage risk and are common in marketplaces for traditional asset classes," giving them "more control over order execution and trading strategies."

He went on to say that from today, it is possible to "place buy or sell Stop-Limit orders on all order books using the Gemini ActiveTrader™ interface, as well as our REST and FIX order entry APIs."

Here is how a stop-limit order works:

A Stop-Limit order has a Stop Price, a Side, and a Limit Price. When the Last Trade Price crosses the Stop Price on either the order book or the Gemini Auction, a Limit order will be placed on the Side at the Limit Price associated with the order.

Yesterday, Gemini launched its referral program, whereby if you introduce a friend to Gemini, both you and your friend earn $10 in Bitcoin (BTC):

There are three requirements you need to be aware of:

  • Your friend must be a first-time Gemini user.
  • Your friend will need to trade at least $100.
  • Your friend will need to verify his/her account within 30 days of registering on Gemini.
