Log In Interface Models
Here, I present you three models of log in page for fintech apps. Most of them use phone number as main identification data for the user.
The first model (model) use one button either to sign up or log in. I think this is the most efficient, cause system will automatically check your number, either you already have account or not. And it also help you fill the form, cause it will save your number before. But, some user find this model force you to give your number, which is sometimes it's a private data. Well, company will love it, but some users dislike it.
In the second model (middle), users have to choose their action first. This model is used when the sign up process only needs several information from the user, so you can use finish it in one page.
The last model is similar to the second model, when users have to choose their action. This is the most popular model. You can easily find this model everywhere. The sign up link will direct you to the register form. For the insecure user in the first model, this can be an option, cause you don't have to give your number in the beginning.
I hope you enjoy it. If you have something, maybe some advices or opinions, feel free to share on the comment ^^ Thank you
