imap
OAuth credential MAnager.
Many IMAP/SMTP clients, like msmtp, fdm, isync, aerc, neomutt or mutt can use OAuth2 access tokens but lack the ability to renew and/or authorize OAuth2 credentials. The purpose of oama is to provide these missing capabilities by acting as a kind of smart password manager. In particular, access token renewal happens automatically in the background transparent to the user.
