How To – reset Admin password on Synology DS218+/ DS718+ / DS918+ and others
Every Synology NAS server comes with a RESET button, which contains the following two types of modes:
- The first reset mode allows you to reset the administrator login credentials and network settings to default settings if you have forgotten your password, want to move your Synology NAS to another network environment, or need to assign a new IP address.
- The second reset mode will wipe out all the system configurations, allowing you to re-install the operating system DiskStation Manager, which is shortened as DSM. All of the reset functions in the first mode are included in the second mode as well.
This article will guide you through the steps of using the RESET button.
- If you only want to change the administrator password, you can simply go to DSM > Options > Personal > Account to change the password, without needing to reset your Synology NAS.
- After your Synology NAS has been reset, the data on the Synology NAS will remain intact. However, before you reset your Synology NAS and re-install DSM, we highly recommended you to launch the Backup & Replication service (available on DSM 5.2) or the Hyper Backup package (available on DSM 6.0 and above) on your DSM, so as to back up your data and system configuration settings in case unexpected data loss occurs.
