Inability to access root account for PGAdmin - Mailing list pgadmin-support

Hello,

My name is Perry DellaValle and our company, BowTie Medical, utilizes PGAdmin for our Postgres SQL database. I wanted to reach out because we are unable to access our root/admin account right now. The username is rdsadmin, but we are unable to log in. Is there an ability to reset passwords so we can gain access to this account again? 

We have had a couple of employees leave that had responsibility for these accounts but did not share the information during a knowledge transfer. So, I am reaching out to see what my options are. Please feel free to email me or call me to gain more information but I am looking to gain access asap. Let me know what other information you need in order to get us access to our admin account.
