Could not validate OTP


#1

Receiving “Could not validate OTP” for the last few days, I assumed it was because I was outside of the US. But now that I am home, I get the same problem on a machine i’ve developed on for years and a phone I’ve had for years as well.

Any Ideas?

Hey there.

OTP authentication relies on a time offset to generate your codes. Ensure your clock is properly in sync with the time servers. Even up to a 30-45 second drift can cause OTP issues.
