Sometimes these codes go to your spam or junk folder. In Gmail, they may also go to your Promotions or Social folder, and in Outlook they may go to your Other tab. Please look in those locations for an email from MeaningSphere.
In addition, if you are using an email aggregator, you may need to check the native app for the email address you used. Email aggregators allow you to collect your emails from different email addresses and services in one app. For example, if you have a Gmail email account but primarily view those emails in your Apple Mail app, you might need to log into your Gmail account directly to see if the passcode went to one of your secondary folders or spam.
If you still do not see it, click “resend passcode” to receive a second code to your email (if the first one ends up coming through, use the most recent passcode). If that still does not work, please submit a support ticket by clicking the purple Support button on the bottom right of this page.
