# How to change passwords for the Control Software accounts on the MiSeq i100 Series Instrument

**Background**

MiSeq i100 Series Control Software User accounts will require a password to login, and this password will need to be updated at regular intervals. Administrators and Sequencer Operators accounts can update their password when prompted by a password expiration notification. Administrator accounts can reset Sequencer Operator and Administrator account passwords at any time.

When an Administrator resets a password for another User account, the User can sign in using the temporary password and then set their new password.

**To change the password**

1. Initialize the MiSeq i100 Series Control Software and log in to an Administrator or Sequencer Operator account.
2. Select the **menu icon** in the upper-left corner.
3. Select **Change password** at the bottom (**Figure 1**)
4. Enter Old password, New Password, then Confirm New Password (**Figure 2**).
5. Select **Save** when finished.
