And for the record, the hash names are ARGON2I and ARGON2ID (see doveadm

pw -l )

With dovecot from the dovecot.org < http://dovecot.org> repo:

# doveadm pw -s ARGON2I -p secret

{ARGON2I}$argon2i$v=19$m=32768,t=4,p=1$bt96TSr3nVrho2SRhnNP0A$h7LYiqkw/4s6d1d+0Xpe+VUE3aISPnkYq/R7QqPRntk

Also from dovecot.org < http://dovecot.org> repo:

doveadm pw -s ARGON2I -p secret

Fatal: Unknown scheme: ARGON2I

It works for me over here:

[wash@waridi ~]#/opt/dovecot2.3/bin/doveadm pw -s ARGON2I -p secret
