Connected apps
An app such as BokFai, an accounting firm's desk, can ask to read the files in your mail. It sends you to MailFai, you see what it asks for, and you allow it or not.
- It sees the files you have received, with each mail's sender and subject, and opens a file when you ask it to.
- It never sees the text of your mail or your passwords, and it cannot send, change or delete anything.
BokFai may also ask to open your mail in its own desk. Then MailFai itself opens there, under BokFai's binders: you read, write, send and organise your mail as here, and put a file in a binder with Put in binder…. Your passwords, your sign-in, two-step codes, storage and deleting your account stay on MailFai, and open here in a new tab.
Settings → Security → Connected apps lists what you have allowed and when it was last used. Disconnect cuts an app off at once, the mail in its desk too.
