unable to reproduce on local

[tranvantoan-qn]

Maybe try it on ANDORID/IOS (as showing in attached video here ) may help you reproduce it easier. I'm sure it will happen

[ZhenjaHorbach]

I think the problem is different

The main problem I have identified is
This is that when entering the magic code we only have 5 attempts

If we make 4 incorrect entries, then we will be able to enter on 5

So for me it's a backend problem.

But from our side

Proposal

Please re-state the problem that we are trying to solve in this issue

After several unsuccessful attempts we cannot login even with the correct code

What is the root cause of that problem?

Theory(We have an unlimited number of attempts)

What changes do you think we should make in order to solve the problem?

To add a little clarity to the situation
We can update the text after several unsuccessful attempts so that the user requests a new code

To do this we can add a failed attempts counter
And when reaching 5 failed attempts, we can ask the user to request a new magic code in the text error

What alternative solutions did you explore? (Optional)

Proposal

Please re-state the problem that we are trying to solve in this issue.

Despite entering the CORRECT magic code, the user is UNABLE to log in

What is the root cause of that problem?

This is because any time we change a digit in the OTP input, we'll send the API call again. When it's called too many times (>5 attempts), we'll be blocked from entering more and have to request a new code.

What changes do you think we should make in order to solve the problem?

1. We should make the error clear if we're being blocked due to too many attempts, currently it's still sending Incorrect magic code. Please try again or request a new code., which misleads the user. We can use something like You've attempted too many times. Please request a new code.. This should be fixed in the back-end to return the correct message.
2. We should adjust the UX since this scenario can happen very frequently. Let's say if the user sees a wrong outdated OTP and enters it. Then realize the issue and modify the code. They'll almost for sure face this issue because by the time they edit all 6 digits, they would have attempted 6 times already because each digit change is an API call.

Some options to consider:
a. Clear all the digits if the OTP is incorrect (this is the same as what Apple does when trying to login to Apple ID)
b. Only auto submit the OTP if the digits are filled and the user currently is focused on the 6th digit. This is to make sure if the user changes the OTP completely, they'll submit the API call only once after they change the last digit. If the user only needs to change 1 digit in the middle, they can always click Sign in to submit the OTP manually.
c. Same as b, but never submit the OTP if it failed the first time. The user should click the Sign in button manually once they're done fixing the OTP. The button copy can optionally be changed to something like Validate and sign in in this case to be clear.

Once we decide on the UX, the change should be straight forward.

Proposal

Please re-state the problem that we are trying to solve in this issue.

The user enter an incorrect magic code and then modify individual digits, the user unable to log in even when entering the correct code.

What is the root cause of that problem?

After an incorrect OTP attempt, if a user modifies individual digits without clearing out all fields, the length of the OTP value remains six.

src/CONST.ts:    MAGIC_CODE_LENGTH: 6,
src/components/MagicCodeInput.js:    maxLength: CONST.MAGIC_CODE_LENGTH,
const validateAndSubmit = () => {
...
if (!props.shouldSubmitOnComplete || _.filter(numbers, (n) => ValidationUtils.isNumeric(n)).length !== props.maxLength || props.network.isOffline) {
            return;
        }
...

This results in the system believing that a complete OTP has been entered, which in turn triggers the API call for validation.

What changes do you think we should make in order to solve the problem?

Clear the OTP fields upon a failed verification, so It forces users to re-enter the entire OTP. By clearing the code after a failed verification, the length of the OTP value gets reset. This ensures the condition for making an API call (all fields being filled) isn't met until all six fields are populated again.

[rojiphil]

Can be considered dupe of #28019 as the final solution arrived at that issue should also resolve this issue.

[parasharrajat]

Yes, it is a duplicate. @stephanieelliott

[sakluger]

Thanks for finding the dupe! Closing in favor of #28019.
