I recently encountered someone who was interested in an accessible password manager, so thought I'd share if anyone else was interested. Digging around in some comment sections I came across [KeePass], its free, open source, multiplatform, and offline only, which depending on how you look at it is much more secure. I ran some tests on it and it seems completely accessible with NVDA, when first loaded you'll need to create a password protected data vault, therein you can store keys that contain a web address, login name, and password. You can move along the taskbar and automatically open a browser to the one in the selected key, and us an auto type option, or copy your login name or password to the clipboard. If you plan on using your passwords on a different computer you'll need to ensure that it has Keepass installed, and you can either use a USB stick or some other means to copy your data vault over.
Its also been used by some NASA agencies like C3RS and ASRS, so there's that. If anybody else has any other password managers they use or want to share, feel free.
