[AC Question]

How do I unlock the phone if I have forgotten the pattern. Mine is Asus running Marshmallow and so I do not get a link to unlock it using Google Account after repeated failure attempts to provide a pattern. I do not want to lose data.

Is the pattern your primary unlock method, or the backup method?

Welcome to Android Central! If you forgot the pattern and you don't get that Google account prompt after repeated failures, then you're stuck. There's no way to circumvent that security (otherwise, there would be no point to that security). If your data is that important, your password/PIN/pattern should be just as important -- in the future, write it down on a piece of paper and keep it somewhere secure, like a safe.
