Testing MFA against sandbox credentials

[favistech]

Hello,

I'm trying to trigger the MFA when creating an item but I always get an INVALID_CREDENTIALS error. I've tried different combinations for the password making sure username is: user_good. I've tried different institutions including the five supported sandbox only institutions. Any suggestions?

You can trigger any type of MFA flow that Plaid supports when creating an Item. Do so by using username user_good and modifying the password

@favistech - Can you confirm that you're using the Sandbox API environment (sandbox.plaid.com)? That's the only environment that supports the test credentials

Try:

username: user_good
password: mfa_questions_2_2

That will trigger two rounds of MFA questions, where each round will have two questions. See the sandbox docs for complete docs.

@michaelckelly confirmed sandbox usage and that password worked and triggered MFA as expected, thank you!
