Some links on Chrome not prompting to save passwords (when Firefox and Safari do)

Posted by jpluimers on 2022/01/20

For quite some time now, Chrome (think years) refuses to prompt for saving passwords whereas Firefox and Safari do prompt and save them, even for site types that it used to save passwords for in the past.

It has been annoying enough for too long now that I tried to do better than the Google searches I used back when I saw this happen first.

Below are some links based on new searches (starting with [Wayback] adding a password in chrome settings – Google Search); hopefully I can try them after I made a list of sites that Chrome does not show the password save prompt for.

Solutions I tried that failed (but maybe useful for others):

Solutions still to try:

Winbox configuration files

Posted by jpluimers on 2021/12/31

A few notes:

  • WinBox configuration files are under %APPDATA%\Mikrotik\Winbox
    • The subdirectory sessions contains binary *.viw files that seem to represent “view” configurations (the positions, dimensions and other properties of the open Windows in a Winbox session) where the * of the name seems to be an IPv4 address of a machine.
    • Directories named like 6.40.3-2932358209 and 6.43.13-695307561 contain configuration files that seem to determine what WinBox features a certain RouterOS version should reveal; files in those directories seem to always be these:
      • advtool.crc / advtool.jg
      • dhcp.crc / dhcp.jg
      • hotspot.crc / hotspot.jg
      • icons.crc / icons.png
      • mpls.crc / mpls.jg
      • ppp.crc / ppp.jg
      • roteros.crc / roteros.jg
      • roting4.crc / roting4.jg
      • secure.crc / secure.jg
      • wlan6.crc / wlan6.jg
    • There are binary files Addresses.cdb and settings.cfg.viw
    • A text file named sessionpath contains the expanded path %APPDATA%\Mikrotik\Winbox\sessions

The *.crc files contain a CRC code, presumably on the contents of the correspoding *.jg file. The *.jg files seem to contain some kind of JSON.

Reset MikroTik through LCD TouchScreen when reset button procedure fails

Posted by jpluimers on 2021/12/13

I wanted access to a supposedly reset a MikroTik [WayBack] MikroTik CRS109-8G-1S-2HnD-IN, but the default credentials did not work. Somehow, keeping the reset button pushed for almost 20 seconds also did not reset+reboot it.

Luckily, the default PIN code was still 1234 ([WayBack] Manual:LCD TouchScreen: PIN code – MikroTik Wiki) so I could reset it ([WayBack] Manual:LCD TouchScreen: Reboot and Reset Configuration – MikroTik Wiki).

After this, I changed credentials and PIN, documented configuration and credentials, and ensured there is a back-up of that documentation available.

Note: fiddling with power and reset button might have worked, though it is odd the CRS109 documentation does not mention this. PIN code worked faster, so that’s what solved my issue first.
