Clear your profile's password and try setting it to not remember it. Then launch the pack and put in your password (make sure your email in the launcher is the one used by your Mojang account; it should be but always good to double check).

And email you the solution? No thank you. That's what these forums are for.

ok hay for the future this is how I fixed it : go to were the launcher is and delete authlib and launch it.
