unlock password?

[Maryji]

I've password protected a section in OneNote but can't unlock it so I can go
back to the section. What do I do?

Are you asking how to get into a password-protected section for which
you've forgotten the password or about the mechanics of unlocking the
section whose password is known?

If the former, you're unfortunately out of luck.

If the latter, click on the section tab then click anywhere on the section
body. A password prompt should appear.
