IPv6 for home internet is changing every day
Since the "upgrade" to IPv6, my public address is changing every day and wreaking havoc with my secure logins for web properties I manage. I don't reboot my modem every day, so it's not like it's fetching a new IPv6. My IPv4, on the other hand, is quite static.
Why does this change every day, and is there a way to decrease that frequency?

The DHCP/DHCPv6 servers are upstream from your modem, and there is nothing you can do about their configuration.
When they are working on stuff in your area, leases can change quite frequently (hours. even less sometimes). Eventually, the lease times extend, but that can take quite some time if there are "upgrades" going on or power fails in your area. DHCPv6 was unstable with the renewal to the point of being unusable in my location for quite some time, so I had it disabled for about a year (IPV4 only). That has only recently changed.
Perhaps that's an option for you. Or a static business account if you have to. Or change authentication methods on whatever you are trying to get to so the origin doesn't matter -- if that is the issue.
