I'm reading the Asterisk book, 2nd edition, and it describes how one
can set up voicemail to be delivered by IMAP to a voicemail folder.

Or is there a way to set up Dovecot to allow a second user to login
to a specific IMAP folder in all accounts, in the same way the local
delivery agent has write access to all users' mailbox?

One possible solution is that you grant Asterisk access to the
mailboxes with as a master user with a (strong) master password. See
the wiki for more information:

I'm wondering how one would set up auth for this? Asterisk needs to log in to the account to deliver the voicemail and to check its state, but I wouldn't want to put everyone's mail password in plaintext in Asterisk's voicemail.conf file. Not sure, but have you tried to use pre-encrypted password like "{HMAC-MD5}asfgasf7a9s6 f865sf..." ? Dovecot supports encrypted passwords. Would I set up a separate IMAP account for each user to hold their voicemail, and use simple passwords (such as the PIN they use for phone access to voicemail) in the Asterisk config? Or is there a way to set up Dovecot to allow a second user to login to a specific IMAP folder in all accounts, in the same way the local delivery agent has write access to all users' mailbox? I think shared folders and virtual user setup is right choise here. Set up virtual users sharing one real uid (to easy avoid any access rigthts problems). Share their "Voicemail" folders for "Asterick-deliver-user". Deliver messages to appropriate shared folder in "Asterick-deliver-users" account. Sharing folders for such virtual users can be easy done using symlinks/ hardliks as they all share one real system uid.
