Your appearance

{{< figure src="assets/profile-cards.jpg" caption="Profile cards showing display name, avatar, and header" >}}

You can change how your profile appears to others by navigating to Settings > Profile > Appearance.

Display name

Your display name is shown to other users before your address. You can set a display name up to 30 characters by default.

Bio

Your bio is a short description of yourself that is displayed as a note on your profile. You can set a bio of up to 500 characters by default. All links are counted as 23 characters, no matter how long they actually are, so there is no need to use a link shortener to save characters. In fact, using a link shortener is actively discouraged.

Avatar

Your avatar is an icon that is displayed next to your posts and is part of your visual identity. You can upload an avatar as a PNG, GIF, or JPG image up to 2MB in size. This image will be downscaled to 400x400.

Header

Your header is a banner image shown at the top of your profile, as well as in profile cards used in follow lists and account directories. You can upload a header as a PNG, GIF, or JPG image up to 2MB in size. This image will be downscaled to 1500x500.

Profile flags

You can set certain flags on your profile to let others know how you use Mastodon.

![]({{ relUrl "/assets/bot-flag.jpg" }})

Locked account

By locking your account, two things will happen:

• New followers will not be automatically accepted, but will instead require you to manually approve them.
• A lock icon will be shown to others, to let them know that their follow will not be immediately accepted.

Bot account

Enabling the bot flag will add a bot icon to your profile. This icon will let others know that your profile may perform automated actions, or might not be monitored by a human. Other software may choose to treat bot profiles differently, but Mastodon currently treats the bot flag as a visual indication only.

Profile directory

Opting in to be listed on the profile directory will make your profile discoverable through a feature that allows browsing through profiles.

Profile metadata

Profile metadata is a way to add extra information to your profile that is easy to skim. You have 4 rows where you can define the label and the value. For example:

Label	Content
Age	25
Country	Germany
Pronouns	he/him
Website	https://example.com

It’s completely up to you what you put there. The content can contain mentions, hashtags, custom emojis and links.

Link verification

Document-based verification and blue ticks are not possible without a central authority. However, Mastodon can cross-reference the links you put on your profile to prove that you are the real owner of those links. In case one of those links is your personal homepage that is known and trusted, it can serve as the next-best-thing to identity verification.

{{< hint style="info" >}} Because Mastodon can be self-hosted, there is no better way to verify your identity than to host Mastodon on your own domain, which people already trust. {{< /hint >}}

If you put an HTTPS link in your profile metadata, Mastodon checks if that link resolves to a web page that links back to your Mastodon profile with a special rel=me attribute. If so, you get a verification checkmark next to that link, since you are confirmed as the owner. Likewise, Mastodon puts rel="me" on the links within profile metadata. The link might look something like this:

<a href="https://social.example.com/@username" rel="me">Follow me on Mastodon!</a>

More precisely, Mastodon will validate the link under the following conditions:

• It is not within an iframe (note that some "block-based" CMS software may wrap block elements within iframes)
• Since 4.0: the hostname does not change after IDN normalization
• it starts with HTTPS
• the resolved page contains at least one a or link tag with a rel="me"
• the href attribute on one of those elements is equal to the URL for your Mastodon profile

Alternatively, validation will occur if the resolved page's first link has an href value that redirects to your Mastodon profile's URL (such as through a link shortener).

{{< hint style="info" >}} Make sure to save your profile after adding the rel-me link to your web page! The verification process is triggered when you save your profile, and may take some time before completing. If you have added the rel-me link and verification is not working, then try deleting the link, saving, re-adding the link, and saving again. {{< /hint >}}
