Is there a limit to how many credentials SSMS can remember?

Using SQL Server Management Studio that came with SQL Server 2008 R2, I make connections to the same server using a number of different sets of SQL Server Authentication credentials. On my development machine, I use the Remember password checkbox extensively to avoid having to look up the password each time.

When I choose a Login which I have previously connected with (using Remember password), the Password entry field gets populated with asterisks, and clicking Connect allows me in - most of the time. But sometimes, with no pattern that I can discern, on choosing a previously-used Login, the Password field will prepopulate with asterisks, but clicking Connect tells me the login fails. I enter the password, click Connect, and get in, and then typically the next time I use the same login it will work.

My suspicion is that there is a maximum number of credentials that SSMS is prepared to remember, and only the most-recently-used n credentials are actually remembered, but I can't find any mention of such behaviour in the documentation.

Is there a known limit on how many credentials SSMS will remember?

It is still a bug (sql server 2008 - 2014 (version 12.0.2000.8 still affected)) as highlighted below :

SQL Server 2012 Management Studio spuriously forgets password, despite being set to remember it.

You can vote up the connect item to get it HOPEFULLY fixed if you are experiencing the bug as well.

%UserProfile%\AppData\Roaming\Microsoft\Microsoft SQL Server\100\Tools\Shell\SqlStudio.bin

might have a limit but I don't know of any kind of hard limit.

BTW, how big is your sqlstudio.bin file now ?
