Any idea on how to enter OTP when using the MQL5 VPS migration service?
One Time Password?
may be ... i have no idea ...
What one time password?
Are you talking about MQL5 VPS?
If not, contact your (other) VPS provider.
Yes, MQL5 VPS.
One time password is a second level log in authorization, generated on mobile phone. MQL5 VPS service, doesn't allow entering of OTP when migrating EAs to virtual server. Hence, log in failed on virtual server.
That has nothing to do with MQL5 VPS, its for extra account security.
