MC has a “Directory hotlist” which funcitons as bookmarking for locations (paths).
For FTP credentials storing the ~/.netrc file can be used, but CAUTION because passwords are saved in plain text. A simple, but not 100% secure workaround is
chmod 600 ~/.netrc
Sample content (syntax) of .netrc:
machine EXAMPLE.COM login USERNAME password PASSWORD
