Some Email servers, such as Yahoo, have added an improved security protocol named two-step authentication. MailWise supports this, but to sign in to you account via MailWise you may need to create an app password for your account. MailWise supports Two-steps Authentication for Gmail, Yahoo, Office365 and Outlook (Hotmail) accounts.
If you add an account with Two-steps Authentication enabled, once you enter your credentials, you will always get the "failure" pop up message, eg Gmail account with 2 steps authentication:
Do not panic. For Gmail - Just click on the link provided in the pop up.
Please make sure you follow ALL instructions written at the support pages of Gmail, Yahoo, Office365, AOL and Hotmail to configure and use the 2 steps authentication security enhancement.
