# Reset user password
|
||
|
|
|
||
|
|
With MySQL or PostgreSQL backends, you can generate a password hash with
|
||
|
|
`openssl` or `doveadm` command first, then replace old one with this newly
|
||
|
|
generated one.
|
||
|
|
|
||
|
|
For example:
|
||
|
|
|
||
|
|
* Generate a salted MD5 password hash with `openssl` (plain password is `123456`
|
||
|
|
in this case):
|
||
|
|
|
||
|
|
```
|
||
|
|
$ openssl passwd -1 123456
|
||
|
|
$1$2dQ48hyz$.mCLeDSdPkP3fxVmARsB.0
|
||
|
|
```
|
||
|
|
|
||
|
|
Or, generate password hash with `doveadm`:
|
||
|
|
|
||
|
|
```
|
||
|
|
$ doveadm pw -s 'ssha' -p '123456'
|
||
|
|
{SSHA}MU5Y8OfD9HylnHk4UQaVyaJf6Lugx6vt
|
||
|
|
```
|
||
|
|
|
||
|
|
* Reset password for user `user@domain.ltd` and `another-user@domain.ltd`:
|
||
|
|
|
||
|
|
```
|
||
|
|
sql> USE vmail;
|
||
|
|
sql> UPDATE mailbox SET password='$1$2dQ48hyz$.mCLeDSdPkP3fxVmARsB.0' WHERE username='user@domain.ltd';
|
||
|
|
sql> UPDATE mailbox SET password='{SSHA}MU5Y8OfD9HylnHk4UQaVyaJf6Lugx6vt' WHERE username='another-user@domain.ltd';
|
||
|
|
```
|
||
|
|
|
||
|
|
With OpenLDAP backend, you can reset it with phpLDAPadmin or other LDAP client
|
||
|
|
tools, `SSHA` is preferred.
