Users Not Receiving a MFA Code
Plaid supports one-time MFA access codes for a select number of institutions. These institutions will send an access code via SMS or email, and these codes must be entered in Plaid Link to complete the authentication process.
If you did not receive the access code, most likely, the contact information their institution has on file is outdated. To resolve this, check the phone number and email on file with your institution and update these details if needed. The other possible reason is that your network provider has not enabled sms short codes. To resolve this, reach out to your network provider and enable sms short codes or try two factor authentication via email. Once updated, go through the Plaid flow again. If you're still experiencing problems, please let us know by reaching out to firstname.lastname@example.org with a screenshot of the error.
