Translation guide
The English word 'username' refers to a unique identifier used to log into a system or service. In Japanese, it is commonly expressed using the loanword ユーザーネーム or the more native term ユーザー名. This guide covers how to talk about usernames in various contexts, from casual to formal.
Referring to a username in most everyday contexts, such as websites, apps, or computer systems.
The most direct loanword from English. Widely understood, especially in tech contexts.

Your username will be displayed on this site.
A slightly more formal or technical term, often used in software interfaces and documentation. Combines 'user' and 'name'.
ユーザー名とパスワードを入力してください。
Please enter your username and password.
ユーザー名は半角英数字で入力してください。
Please enter your username using half-width alphanumeric characters.
Literally 'account name'. Used when the username is specifically tied to an account. Common in online services.
アカウント名を忘れた場合は、再設定してください。
If you forgot your account name, please reset it.
Specifically 'login name'. Used when emphasizing the name used for logging in.
ログイン名はメールアドレスです。
Your login name is your email address.
Refers to a nickname or handle used in online communities, forums, or social media. Not typically used for formal account usernames.

Phrases used when requesting or providing a username in conversation or forms.
Standard way to ask 'What is your username?'. Casual to polite depending on context.

Polite request: 'Please tell me your username.'

Pattern for stating your username: 'My username is ~.'

Often used interchangeably with username in login contexts, especially when the identifier is not a name but an ID.

Both are common. ユーザーネーム is a direct loanword and feels slightly more casual or modern. ユーザー名 is a hybrid word (ユーザー + 名) and is often preferred in technical documentation and formal settings. In most everyday situations, they are interchangeable.

ユーザー名は6文字以上にしてください。
