First of all I'm very happy with the product and have been for quite a while. I was wondering if any support for 2FA will be added in the near future? Specifically yubikey as an extra layer on top of your masterpassword.
Thank you for contacting us. We not only use an account password, but also use a device created random account key as well. We require customers to save and keep a hold of this account key and customers need to authenticate the account key in order to sign in to their accounts. You can read more about our security model here: https://m7software.freshdesk.com/support/solutions/articles/36000019927-msecure-s-security-model
That said, yes, we are looking into additional security and are looking into Two Factor authentication and different types to offer in the future. However, there is not set plan for when and what types of Two Factor authentication will be offered in the future.
