We take security very seriously. We have 2-factor authentication for all login attempts. We also have it for all payments, in this case, through a sms verification code, to make your account more secure.
You can also log in to your account on the web interface by confirming the log in attempt through our Revolut Business mobile app or with the "Log in with Google" options.
Note: At this moment, sadly we don't support emails under '.ru' domains.
