2FA (2-factor authentication) is enabled and is triggered when someone accesses your account or perform any account operations. An OTP (one time password) is sent to your registered email id for verification.
Do you have any plans for incorporating 2FA for mobile? Thanks.

At the moment not, But I will definitely share your Idea with our team.
Coinexx has been really good about listening to traders. I would recommend reaching out to them and making any suggestions that you have. The more that people reach out about a particular issue, the more that they are likely to push for it.
