Is Your Pet's Name a Safe Password? We Tested the Most Popular Ones
Millions of people use their pet's name as a password. Most of them pick from the same handful of names, and attackers know the list by heart.
Below, we break down the most commonly used pet names in passwords. Each one fails for a slightly different reason, and understanding why helps you fix the problem without abandoning a name you love.
Is Bella a Safe Password?
Bella has topped pet name popularity charts for over a decade. It is the #1 female dog name in the US, UK, and Australia. That kind of popularity is the core problem: when millions of people independently think "nobody else would use my dog's name," and they all picked the same name, attackers get a very short list to work through.
Bella appears in virtually every password dictionary used in real attacks. It is not buried somewhere in the middle. It is near the top, alongside variations like Bella123, Bella2024, and bella!. The word itself is also common in Italian and Spanish (meaning "beautiful"), which means it shows up in non-English password lists too.
What makes Bella uniquely weak: sheer global popularity. No other pet name appears in as many breach datasets across as many languages and countries. If you use Bella alone, you are sharing your password idea with a very large crowd.
Is Max a Safe Password?
Max has a problem that Bella, Luna, and Charlie do not: it is only three characters long. That matters more than most people realize.
Password cracking tools can brute-force every possible 3-character combination in under a second on modern hardware. That means even if "Max" was not a common word, its length alone makes it trivial to crack. The fact that it is also one of the most popular dog names just makes it worse. It gets tested early in dictionary attacks and falls instantly to brute force.
Adding numbers helps less than you would think. Max123 is six characters, still very short, and "123" is the most predictable suffix in existence. Max2026 is seven characters with a guessable year. You need to add a lot more length before Max becomes a viable foundation.
What makes Max uniquely weak: extreme brevity. Other pet names are at least 4 to 6 characters. Max gives attackers almost nothing to work through, regardless of what you append to it.
Is Luna a Safe Password?
Luna has surged in popularity over the past five years. It is now one of the fastest-rising pet names in the US and Europe, which creates a specific kind of vulnerability: attackers update their word lists based on trends.
Password dictionaries are not static files from 2010. Security researchers and attackers both track naming trends, and when a name spikes on pet registries, social media, and baby name lists simultaneously, it gets added or promoted in attack dictionaries. Luna is exactly in that sweet spot right now.
There is another angle people miss: Luna is also a common word in multiple languages (it means "moon" in Spanish, Italian, and others), a popular brand name, and a frequently used username. That cross-domain popularity means it appears in password lists sourced from gaming breaches, social media leaks, and forum dumps, not just pet-related contexts.
What makes Luna uniquely weak: trend-driven predictability. Its rapid rise in popularity means it is being actively promoted in current attack dictionaries, not just sitting in legacy lists.
Is Charlie a Safe Password?
Charlie is unusual among pet passwords because it blurs the line between pet name and human name. It is simultaneously a top-10 dog name and a common first name for people. That dual usage creates overlapping risk.
Attackers do not maintain separate "pet name" and "human name" lists. They combine everything. Charlie appears in general name dictionaries, pet name lists, username databases, and historical breach data. It gets tested from multiple angles during an attack, not just one.
It is also worth noting that Charlie is commonly used as a base for "personalized" passwords like Charlie2019 (birth year of pet or child) or CharlieB (name plus initial). These feel creative but follow patterns that rule-based attacks generate automatically.
What makes Charlie uniquely weak: dual-context exposure. It is attacked as a pet name and as a human name, which means it appears in more word lists and gets tested more frequently than names that only fit one category.
Buddy, Rocky, Daisy, Milo and Others
These names round out the top of most "popular pet names" lists, and they all share the same fundamental issue: they are short, common, and widely shared on social media.
- Buddy doubles as a generic English word, so it appears in standard dictionary attacks even without pet-specific lists.
- Rocky overlaps with the movie franchise, which means it has been in password dictionaries since the 1980s.
- Daisy is common across pet names, human names, and flower-related passwords. Similar cross-domain problem to Charlie.
- Milo is trending upward fast, similar trajectory to Luna. Also a brand name (chocolate drink) in parts of Asia and Australia.
Quick Comparison
| Name | Length | Primary Risk | Appears In |
|---|---|---|---|
| Bella | 5 | Global overuse across languages | Pet lists, Italian/Spanish dictionaries, breach data |
| Max | 3 | Extremely short, brute-forced in seconds | Pet lists, common word lists, name databases |
| Luna | 4 | Trending, actively rising in attack dictionaries | Pet lists, multilingual dictionaries, gaming/social breaches |
| Charlie | 7 | Dual context (pet + human name) | Pet lists, human name databases, username dumps |
| Buddy | 5 | Common English word | Standard dictionaries, pet lists |
| Rocky | 5 | Pop culture overlap (decades of exposure) | Pet lists, pop culture dictionaries |
| Daisy | 5 | Cross-domain (pet + human + botanical) | Multiple overlapping word lists |
| Milo | 4 | Fast-rising trend, brand overlap | Pet lists, brand name lists, trending name databases |
How to Actually Fix a Pet Name Password
You do not have to stop using your pet's name. You have to stop using it the way attackers expect.
The most common "upgrades" people try, such as adding 123, a birth year, or a single !, do not work because those are the exact modifications attack tools test automatically. Read more about
why these patterns fail.
What actually works is combining your pet's name with unrelated words, placing numbers and symbols in unexpected positions, and pushing the total length past 14 characters. The goal is to break the pattern, not decorate it.
Weak vs Strong Examples
| Weak | Why It Fails | Stronger Alternative | Why It Works |
|---|---|---|---|
Bella123 |
Most common name + most common suffix | Bella$kettle!rain42 |
19 chars, unrelated words, mid-placed symbols |
Max2026 |
3 char name + predictable year | Max.plank!52vault |
17 chars, random word + number + word |
Luna! |
Short name + trailing symbol | Luna_spoke_44_craft |
19 chars, passphrase style, easy to type |
Charlie2019 |
Common name + birth year pattern | charlie&Frost_27_lamp |
20 chars, no predictable year, mixed case |
Notice that the stronger versions are not random gibberish. They are readable phrases you can actually memorize. The security comes from length and unpredictability, not from being impossible to remember.
