I speak the following languages:

• Mixed English (mostly American-style, but I use certain words from other dialects)
• US English (likely the most intelligible accent of it)
• UK English (still working on it, but it’s quite accurate)
• Misc English (multiple accents and vocabulary ranges)
• European Portuguese (my native language, news anchor accent)
• South Alentejo Portuguese (ve4y specific accent)
• Brazilian Portuguese (emulated accent, 80% accurate)
• Spanish (European, still work in progress)

.

And increasing the hash size, to mitigate collusions? I would assume that it takes much longer to find collusions that result in a specific password’s hash, if there are more digit amounts, correct?

Even it they (WhatsApp) still provide reliable E2EE, they have lots of metadata that is not encrypted, and that they actively share with their “advertising partners”.
