Binance Expands YubiKey Support for Two-Factor Authentication (2FA)

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:

Coinbase Delivers Raft of Improvements, Including ETA On Crypto Transfers

  • Coinbase adds instant top-up
  • And ETA on crypto transfers

Top-rated cryptocurrency exchange Coinbase has activated two improvements to its platform: unified sending-top-ups and crypto transfer ETAs (estimated time of arrival). The improvements are detailed in a blog post, in addition to the recently-added transaction-batching which significantly reduces transaction fees.

Top Up With Sending

This small time-saving feature kicks in when a user is trying to send some crypto but does not have enough of it in its wallet. The new mechanic will automatically purchase the amount of crypto the user want sto send with your funding source, and complete the operation.

This top up feature makes sure to avoid any hangups by only drawing on instant-payment options that the user has already set up.


One of the implications of a publicly verified and operated blockchain is that, the experience is rather more dynamic than what we might find from a centralized service. Hashrates and difficulty levels on Bitcoin’s, and other networks change depending on what is happening in their ecosystems—and all of this affects transfer times.

Now when sending crypto, Coinbase will take these factors into account to estimate how long it will take for the transaction to complete.

In an official blog post, Coinbase recently argued that between Bitcoin and gold—while similar—Bitcoin is the better option as a “safe haven asset” than more traditional gold.

They argue that, while supply of physical precious metals (as opposed to paper trading of them) has become choked in recent weeks and months since the COVID-19 pandemic hit, anyone can still get their hands on “physical” bitcoin by storing it in a private wallet.
