Needing help managing Figma for the company

It looks like someone who is the owner/admin of your Figma project locked those files or, which looks more reasonable, are locked for you because you have a fresh account without any given access.

You need to log with that admin account and give yourself a proper permission for each file, i.e. “can edit”.
Do it here (right mouse button click on the project file in Figma), click “Share”

  and then click the “Anyone” row. And click the “Edit” option

If you have struggles with finding out what the correct email/account is, I’d ask someone who runs finances as most likely such an account is associated with an official corporate email. But even this might not be enough as each file can have a different owner and owners can share/restrict file access.

Hey Paul, Celine from the Figma Community Support here, happy to help!

• For accessing the files with your new account: The easiest way is to have someone with admin access (or from the finance account you were using) invite your new work email to the team with the right permissions. Once added, you should be able to access the files from your new account.
   
• Since you mentioned the files are "all over the shop", it's worth knowing that in Figma, files can be owned by different people and stored in different places (some in a shared team, others in someone's personal drafts). Files in personal drafts are only accessible to their owner, so there's no one-click way to share everything at once. That's why I'd recommend consolidating everything into one team if possible, using your work email as the main owner and transferring key files/projects there. Here’s our guide on how to move a file.
   
• About the files being “locked”: As Tomasz5 said, this usually comes down to permissions. Files can appear locked if your role is set to Can view instead of Can edit.
