I have a QGIS project where I am connected to about 10 databases. The issue I have is that I cannot seem to save the password to disallow repetitive password authentification. After logging in individual databases and working on the project when I pan around a request comes to log in after a few seconds. I have seen somewhere it suggest that I save the password when I do the connection to the database, however in QGIS 3.6, this seems to be different or I cannot get it right, after storing credentials, and not working on the project for a few minutes, when you come back it will ask you for the password again. This link here suggest it is a bug? From QGIS 3.4.5 and 3.6 asks password repeadly to connect to PostgreSQL 10 .
